Reddit is one of the last remaining websites where people are still talking to people. But brands and AI bots want in.

It was AI, of course there is a readout Reddit Real humans talking about literally everything. Information for humans by humans, jealously guarded from AI slop by humans. Except humans may be losing the battle for Reddit, the last real place on the Internet ahead from Fox.

Miya Sato writes about technology for the ver, including a recent piece about Reddit trying to fend off non human users. It started when Mia noticed something on the platform. She is very into skin care and to determine what to buy next. She often goes to Reddit to see what real people, not bots or influencers or marketers, think about a product.
Miya Sato
So the skin care subreddits that I mentioned in my story are actually subreddits that I often read because I want, you know, unfiltered or true opinions about products before I buy them. How is this mask for dry acne prone skin?
Sean Ramas
How can I get rid of my dark circles?
Miya Sato
Would I be a good candidate for microneedling? And I go to Reddit for skincare recommendations quite a bit and I suspected that if you are a skincare brand and you want people to be talking about your product, you will go to these subreddits, because some of these subreddits get like one and a half million viewers a week. You know, they're doing crazy numbers and very, very. They have a very committed and active community. So I was like, if I were a brand and I wanted to market myself, I would probably post on Reddit. And I was curious how the moderators of these skincare subreddits were handling that, because also marketing firms had told me, like, yeah, all our clients, they really wanna know how to crack Reddit. It's really hard. They wanna figure out Reddit. And so I talked to a subreddit moderator who does one of the skincare subreddits, and she gave me a ton of detail about the amount of spam that they were getting. The unfortunate thing is it does mean I end up being more suspicious of smaller brands, even though I would love to see more small brands out in the world. And she sent me one example, which was a thread of someone asking about a certain acne spray, a spray that people use for acne treatment. And someone is the person who posted it asked, like, magic Molecule hypochlorous acid spray, Is it really that good? Recently, I have seen a lot of good reviews about this product. Any of you tried, do you recommend? What's your take on this? And you know, it got like dozens of answers. Some people said, yes, it's one of my favorites.
Sean Ramas
I spray it on after I cleanse my face, then go in with my toner and serums.
Miya Sato
You know, the residency.
Noel King
No, I've used a range of brands, including Magic Molecule. Buy the cheaper brands, they all work the same.
Miya Sato
But one of the answers was from just a random account that said, I
Reddit User (Example Commenter)
haven't personally tried Magic Molecules specifically, so I can't compare. Sorry. But I have been using a similar hypochlorous acid spray from Honeydew Labs and I've honestly really liked it.
Miya Sato
And if you are reading that comment, you probably would think nothing of it. But what you don't see, unless you click over to the profile and do some digging, is that this random account had actually, over the course of several days, maybe even months, and across different skincare subreddits had been recommending the same product over and over and over and using very specific terminology, saying one thing
Reddit User (Example Commenter)
I've noticed when comparing products is that Honeydew Labs uses a 0.02% hypochlorous acid concentration. And it's also accepted by the National Eczema association, which made me feel a bit more confident trying it on. Sensitive skin.
Miya Sato
It was very controlled messaging. And of course the moderators were like, what normal person is going to go across different subreddits and keep pushing this product for no reason? And so that is sort of one of the ways that this new type of spam on Reddit takes shape, which is brands pretending to be normal users on Reddit.
Noel King
And this for Reddit moderators is something what I'm thinking. They can't individually suss it out immediately or it wouldn't be happening. Are they doing the search themselves to try to figure out like, is everything on here real? How are they dealing with this?
Miya Sato
They have a bunch of tools, like some of them are auto moderator tools where basically a bot will look at every submission that comes through and like move some things to a filtered folder where moderators can look at. But one of the funniest things that several moderators actually told me was they keep shit lists of companies that they think have spammed them in the past. So the skincare subreddit told me about this. A weight loss subreddit moderator who I interviewed also said this. They have a running list in the background where if they think you've spammed or astroturfed their community in the past, they keep all those brands names and now they have basically if you mention that brand name, your post will automatically get filtered out. Wow, okay. And you know, the moderators are trying to send a message like, if you spam us, all of the posts that even are not your spam will get filtered out and we will take a closer look at them. So it's really like, you know, they're pretty strict with it. Some the moderators that I spoke to said that they've really seen an increase over the last six to eight months. Maybe I can give you a couple of the numbers that Reddit has released publicly because Reddit has said also that they know that this is a growing problem. So the company said that it removes 25,000 spammy posts and comments a day. They block something like 23 million spam views, and they also tackle sort of like spam upvotes. So that's a way on Reddit to sort of signal agreement. But Reddit knows that it is kind of a new era of spam and they've said that they're using LLMs and other AI powered moderation tools to try to catch this stuff better.
Noel King
Let me ask you something and maybe it Comes down to what Reddit is and always has been. But I will go on Instagram, I will go on TikTok, and my feeling is I don't spend a ton of time on these sites, but my sense is like, half of it is just like crap that's trying to sell me something. It might not be real. It just all feels pretty garbagey to me. I feel like when you wrote this piece, you were saying there are stakes here to Reddit being the thing that, like, must kind of stay pure, must stay away from this. What, what is it about Reddit that makes it important that Reddit has so far managed to resist this?
Miya Sato
I think one part is the concept of like, influencers doesn't really exist on Reddit in the same way that it exists elsewh. Yeah, and if you are an influencer, there are very few places that you can post without getting in trouble. Many, many subreddits have explicit rules saying, you may not self promote here and we will ban you if you do. That is a totally different environment than Instagram where sort of the expectation is that someone is selling you something. These are the wide leg stockings from Alpha Kid. And these things are freaking wide leg. They have these nice big long pockets.
Reddit Moderator
I love these.
Miya Sato
You need to keep your face hydrated. That's what keeps wrinkles away. And that is why I love this calcium bomb stick. I cannot live without it. It is a staple. Now the other part that makes Reddit unique, I think, is that for better or for worse, and deserved or not, Reddit, in the minds of people using the Internet, has come to sort of be associated with real opinions or real people. Which is funny because the platform is anonymous. You know, most people are using just a random username, not their full name. It's kind of stumbled into this reputation of being filled with real helpful opinions and perspectives. And, you know, Reddit has deals with certain AI companies where they allow LLMs to be trained on their, you know, just troves of Reddit data, of real people having conversations. And so I think, you know, over the last few years, as Google search feels like it's gotten worse, and people have gone to places like Reddit to answer their questions. Like, Reddit's stock literally has skyrocketed as being a place where you can find information, where people aren't trying to sell you something all the time, or are they right? Like, that's kind of the part that I wanted to untangle.
Noel King
Does Reddit actually have to become overrun with marketing fake posts? People saying, oh, you should Definitely buy this skin care because they're getting paid to say that for this to be a big problem or does it just have to get to the point where I am suspicious that I'm not talking to an actual person on Reddit and I start doubting the platform itself?
Miya Sato
Yeah, I mean, I think for me personally in the course of reporting this story, I was like, maybe, maybe I shouldn't buy things based on a recommendation from Reddit. You know, like it's, it's a real kind of a new type of problem and a new way of looking at a platform as it relates to sort of AI search too. I was thinking about if these chatbots love to cite Reddit so much for their answers. Can the AI systems detect when something is spam? Can they detect when a comment is coming from a brand or the person who left that comment? If you go to their account, they're always promoting that product. And I am not convinced that Google's Gemini or ChatGPT can suss out when something is promotional and when it isn't because I've written about this before and I know that they can't. So yeah, it's a strange thing where I think kind of the deception on one platform ends up trickling through other places as well as the Reddit thread gets cited by search features and LLMs.
Noel King
Have you changed your buying habits based on what you're seeing now on Reddit?
Miya Sato
I feel like I'm just way slower to buy things. You know, I'm just like, let me keep this in my head. Let me put it on my wish list and do some research to see, you know, what other people, what real people think and also make sure that they have like a good return policy.
Noel King
That was the verge is miya sato. When we come back. AI AI companies love Reddit. AI companies rely on Reddit. AI companies may destroy Reddit. We're going to explain.

You're listening to Today Explained. So Mia, in the first half of the show, we are Talking about how Reddit has always felt like an important and valuable site platform because you are talking to a real human being. And there is something kind of magnificent about that. I gotta say, it turns out it is not just me and you that feel this way. It is also the AI companies that recognize something magnificent is happening. What's it worth to them? Why do they care?
Miya Sato
You know, AI needs to know how people talk. Yeah, these poems are just patchworks of my life in order to make it right, because the models are using vast troves of information of people writing and speaking and singing.
Noel King
It's your birthday, so I know you
Miya Sato
want to ride out and acting. How could you say that? I thought you loved me. And you know, appearing on video.
Sean Ramas

Miya Sato
to create its outputs. So data of people disagreeing, of reasoning, of recommending things is incredibly, incredibly useful. And think about a platform like Reddit, you can find conversations about just about anything and between many, many different people. So that raw text is very valuable. The other thing is this is maybe getting a little into the weeds, but when you search for something, you know, you see those sort of citational links appearing in like chatgpt and whatnot. Those LLMs need something to point back to, and often there is something on Reddit for them to point back to. And we know from data that they love to point back to this platform. It is incredibly helpful, maybe perhaps just because of all the different types of content that is on Reddit. There was data that was compiled for the Verge for the story that I worked on that showed that in May of 2026, across several different LLM tools. So, like ChatGPT and Gemini and Google's AI mode and perplexity, the number one cited domain was Reddit. W citing Reddit more than Wikipedia, they were citing it more than the New York Times, they were citing it more than sort of repositories of scholarly articles. And that tells you something, right? Like that is very, very valuable for when people ask these chatbots questions and want answers and want a link to somewhere to go look at it.
Noel King
Are AI companies actually paying Reddit for the information, like for the ability to look, and stuck it all in.
Miya Sato
They do have licensing deals. They are paid for the data.
Noel King
What has been the response from Reddit users to learning that AI is training on their question about, you know, how to find a great eyelid cream?
Miya Sato
I think overall there is, at least from the moderators I've spoken to There is a real feeling of their communities being invaded, especially with AI slop. They feel like there are more AI generated comments and posts on the communities and they don't like it. It. Many of them have very strict rules around no AI content whatsoever.
Reddit Moderator
We have had a flood of AI content being posted over the last few months on this sub. As of today, we have updated the subreddit rules with the following. No AI. We do not allow AI generated content or AI tools to be posted on this sub. Recommendations of AI, mentions of specific AI tools and posts primarily about AI, will all be removed.
Miya Sato
I spoke to a moderator of a music subreddit and he told me, like, yes, we have record labels secretly coming in and pretending to be users, but the biggest threat to our community is AI generated slop that is coming in. So I think there is in general a feeling of like, we don't want to read spam comments that were written by AI, we want to read comments from real people. But like, can we stop this flow of spam? Can we keep it a healthy, helpful community? You know, those are people who do these jobs mostly unpaid. They're, they're volunteer moderators. So a lot is resting on their shoulders and their ability to keep things fresh and helpful.
Noel King
Okay, I understand AI companies sucking the data off of Reddit and like looking through it and being like, oh, when a person asks for advice on, you know, how to get to a marathon start line, this is how they're going to do it. This is how a person talks or. But you're telling me that AI is also on Reddit, like leaving messages itself. What is the point of that?
Miya Sato
I think a lot of them, in the context of the piece I wrote, is like AI marketing slop. So at least the moderators kind of suspect that brands are deploying bot farms basically to promote like this random moisturizer or, you know, this weight loss boss
Noel King
app or whatever it is about selling stuff often.
Miya Sato
Yes. Reddit interestingly told me that 40% of the conversations on the platform are commercial in nature. Meaning, huh, what should I buy? Doing research about products, reviews about something I did buy? 40%. That is a huge amount for a place that is like presumably person to person discussion. A lot of the conversations that are happening on is about what should I buy. So I found that to be incredibly fascinating and might explain some of the sort of marketing slop use cases that the subreddit moderators are seeing.
Noel King
Okay, so if AI is pointing to Reddit posts as like the definitive answers to search queries, how do I Get from X to Y in the shortest amount of time possible. That seems like it's even more incentive for anybody who has something to. To sell you to get their name on Reddit to try to spam Reddit threads as much as possible in order for people to be, I don't know, reading about them or, or seeing people engage with them. Is that from the perspective of a marketer? Is that right? Is that what's going on?
Miya Sato
A hundred percent, Absolutely. And part of it is like, can we go into these popular subreddits and like, you know, talk to users secretly or transparently? Another tactic that some brands have opted for is actually like, spinning up their own subreddit that they run themselves.
Noel King
Huh?
Sponsor/Ad Voice
No.
Miya Sato
Which is kind of. Which I think in a lot of people's minds, sort of defeats the purpose of Reddit. You know, they want to hear from unbiased sources, not from the brand that you're trying to get an opinion on. But that is certainly happening. And, you know, some marketing firms are like, recommending clients do that in order to maintain control of their message on Reddit.
Noel King
Okay, so the sad question at the end of the day becomes Reddit is so awesome because it is full of real humans. Increasingly, brands, companies would like to make it full of slop in advertisements. Do you think that all of this could ruin the thing that makes Reddit so useful to AI? Like, I'm imagining AI now training on other AI and marketing slop.
Miya Sato
Yeah, I know that's been a concern that, you know, researchers and journalists and stuff have put forward, like what happens when the AI is training on AI generated content. I think beyond that, though, the content doesn't have to be AI slop for it to be unhelpful. It can be written by a PR person somewhere, but be untrue. And that, I think, is also not valuable to people or to the tools that they use. I think what makes Reddit appealing is this idea that you get a bunch of people in a room and you can ask them any specific question and someone could have an answer for you or a perspective. But when those people get replaced with tightly controlled, carefully edited, carefully worded marketing copy, I would just read a press release. Why would I read Reddit? To get that information, you know, and so I spoke with someone at a PR firm and his perspective was like, in order to crack Reddit, you need to be really, really honest about what your brand can offer and what it can't. Which sounds wonderful. I would love for that to happen.
Sponsor/Ad Voice
Yeah.
Miya Sato
But I think that is wishful thinking, and that's not what is always going on. I think what ends up really hurting the platform and all of the sort of tools that are trained on it is that when users start to lose trust in what they're reading. I spoke with a moderator of an indie music subreddit on Reddit, and what they found was they noticed that indie record labels were secretly hiding among the community and only promoting their artists. When people would ask, like, anyone have a music suggestion? And when you find something like that and when you tell the community that, people start to be a little on edge, you know, they start to feel like everything they read that is positive about something is secretly paid promotional content, is marketing, is astroturfed. And I think that is a really bad place to be as a data provider to AI companies, but also as a society generally. Like, I don't want to feel like everything I read is fake, but I think a lot of people feel that way.

Hosts: Noel King & Sean Rameswaram
Guest: Miya Sato (Technology reporter, The Verge)
This episode examines why Reddit is often considered the "last real place on the internet"—a platform where real people discuss virtually everything, and how that reputation is being threatened. The discussion explores the infiltration of spam, influencer marketing, and AI-generated content into Reddit, and why these issues matter—not just to users but also to the future of online information, trust, and AI data training.
Reddit’s value lies in its real, diverse, and human-driven discussions—a treasure trove for both curious users and AI companies. But a rising tide of marketing-driven spam and AI-generated content now threatens its reputation and integrity. Moderators are fighting a difficult battle to preserve authenticity. If trust erodes—for users and for the AI models trained on Reddit—the internet loses not just a vital resource, but a bedrock of online authenticity.
