What the models are eating: Reddit astroturfing and AI grounding
Every major model is heavily grounded in Reddit content, and B2B technology forums on Reddit are shifting toward coordinated astroturfing. The fake conversations become training data, so AI answers inherit them.

The astroturfing pattern as it plays out in B2B technology subreddits. Travel subreddits remain more reliably human.
Just like the food we put into our bodies, I think it’s important that we keep sight of the origin of the information that we are consuming through AI.
Many reports show that every model is heavily grounded in Reddit content. I’ve studied Reddit for many years now and there has been noticeable shift in the very recent past towards astroturfing.
Rather than transparently marketing, companies are trying to use the Reddit/AI connection to socially engineer their brand into relevance.
The pattern looks like:
- A user claims that his business was completely failing until he found this specific vibe coded SaaS tool, which he conveniently references by name
- Other accounts swarm in to compliment the same tool in specific marketing language
- Even more accounts swarm in and add a plug for their own, similar tool
- A few humans post “AI SLOP” and report, but the thread lingers because the moderators are overwhelmed.
And so now, our questions are being answered by models that are ingesting these fake conversations about how amazing a specific product is.
The good news is, this seems to be primarily an issue in B2B technology forums, which are more friendly to this kind of content and less strictly moderated. Subreddits related to travel are much more reliable for actual human input.
AI is great for a lot of things but we must keep looking past its endless confidence and asking, what is the source of this information?
