Reddit deleted four subreddits built to game AI answers
A 60-day experiment that used bots to farm AI mentions ended with every post, link and citation wiped.
Reddit has deleted four subreddits that were created purely to get mentioned inside AI answers. The communities were part of a 60-day experiment run by Otterly, and the case study was shared by Glenn Gabe. According to that write-up, Reddit removed all four at once for breaching Rule 2 of its content policy, after bots were used for upvotes and commenting.
The damage was total. The case study says every post, every comment thread, every ranking URL and every AI citation that pointed at the communities went with them. So the links that were feeding mentions into AI tools stopped existing, not just the accounts behind them.

Why this matters if someone is pitching you Reddit
GEO stands for generative engine optimisation, which is the work of getting your business named in AI answers like Google's AI Overviews or ChatGPT. Reddit threads often show up as sources in those answers, so a trade has grown up around planting and boosting Reddit posts. That is what this experiment automated, and that is what Reddit shut down.
Lily Ray replied to Gabe's post saying she still gets emails all the time from companies selling these tactics. So the pitches are still landing in inboxes even as the method is being removed at the source.
The lesson for a small business owner is narrow but useful. If an agency offers to build you Reddit presence with automated posting, upvoting or commenting, the asset you are paying for can be deleted in one action by Reddit, and everything built on top of it goes too. You do not get a warning period and you do not get the links back.
What to do
If you have an SEO or AI visibility proposal on your desk right now, find the line about Reddit or forum seeding and ask one plain question. Ask whether any posting, commenting or voting is automated, and ask who owns the accounts. If the answer is bots, or if the answer is vague, say no.
If nobody is pitching you this, do nothing. Nothing here changes how Google ranks your own website, and nothing here is a penalty against businesses that have been mentioned in normal Reddit threads by real people.
This is one case study about one experiment, so it is not a Reddit policy announcement or a statement from Google. It is a straightforward demonstration of how fast rented ground disappears when the platform decides it has been gamed.
