There’s something a bit funny going on at Reddit right now. The platform is using AI to fix a problem that AI helped create in the first place. And honestly, it makes a lot of sense once you think about
it.
Large language models have made it incredibly easy for anyone to churn out spam and bot content at scale. If you’ve spent even a few minutes online over the past couple of years, you’ve probably noticed this yourself. Fake comments, coordinated hype, bot accounts, all of it has gotten harder to spot and easier to produce.
Reddit’s answer to this problem is to use the same technology causing it. The platform says it has built new tools powered by LLMs specifically to cut down on spam, even though much of that spam was likely created using LLMs to begin with. It’s a bit ironic, sure, but in the current AI era, platforms don’t really have another option. Fighting fire with fire seems to be the only realistic approach left.
How much spam is Reddit actually catching
Reddit shared some solid numbers to back up its claims. According to the platform, it now blocks around 23 million spam views every single day. On top of that, it catches roughly 25,000 new spam posts and comments daily.
These aren’t small figures, and they show just how much junk content is constantly being pushed onto the platform. Social media companies have been working on automated spam detection for years now, but Reddit says its newer tools are catching spam at a noticeably higher rate than before.
In a company blog post, Reddit explained the reasoning behind this shift. The platform said it now uses LLMs to catch subtle, coordinated patterns of fake behaviour and artificial hype that older systems used to miss entirely. That’s an important distinction. Older spam detection tools were mostly built to catch obvious, repetitive spam. Coordinated fake behaviour that looks more natural is a lot harder to catch without more advanced tools.
Reddit also claims real results from this shift. The company says it reduced users’ exposure to spam by 20 percent between January and March, compared to the three months before that. That’s a meaningful drop if the numbers hold up over time.
How other platforms are handling AI content
Reddit isn’t alone in dealing with this issue, though different platforms are taking slightly different approaches. YouTube, Meta and Instagram all allow AI-generated content on their platforms, as long as creators disclose that it’s AI-made. TikTok has gone a step further, letting users actually choose how much AI-generated content they want to see in their feed at all. That’s a more hands-on approach compared to Reddit’s behind-the-scenes spam filtering.
There’s an interesting side effect to all this too. If platforms get better and faster at detecting AI-generated content, that same technology could help them flag other harmful content more quickly as well, things like hate speech or coordinated harassment campaigns.
That said, experts who study content moderation keep repeating one important point. AI alone isn’t enough. For moderation to actually work well, it needs to be paired with human moderators, not left entirely to automated systems. AI tools are good at spotting patterns at scale, but human judgement still matters for context and nuance that machines can miss.
What this means going forward
Reddit’s approach is a pretty honest admission of where things stand right now. AI made it easier to flood platforms with fake content, and now AI is being used to clean that same mess up. It’s not a perfect solution, but for now, it seems to be one of the few tools powerful enough to keep pace with the scale of the problem.
For everyday Reddit users, this mostly means less obvious spam cluttering your feed and comment sections. But as this arms race between spam creators and spam detectors continues, expect both sides to keep getting more sophisticated. Whether human moderation keeps up alongside these AI tools will likely decide how well this actually works in the long run.
