RedRover sells Reddit AEO to game ChatGPT answers
Key insights
- RedRover openly markets an AI agent network that mass-publishes Reddit content to manipulate how LLMs like ChatGPT select and surface citations.
- Reddit accounts used in AEO campaigns are 'warmed up' with genuine posting histories to evade detection and appear human.
- r/biohackers restricted all new peptide and HRT posts to weekly megathreads after moderators identified systematic brand manipulation targeting LLMs.
Why this matters
Reddit's status as one of the most-cited sources for ChatGPT and Google AI search creates a structural vulnerability: any platform LLMs treat as authoritative becomes a paid-placement surface for commercial actors. The emergence of commercial AEO services like RedRover signals that manipulation has formally shifted from search rankings to LLM retrieval pipelines, meaning AI-generated answer quality is now tied to whoever games source content most effectively. For teams building RAG or search-augmented systems, this exposes a layer beneath the model itself: high-trust community platforms can be poisoned at the content level without any access to model weights or APIs.
Summary
Peptide and HRT companies are systematically gaming Reddit to shape what ChatGPT and Google AI search tell users, using a formal practice now marketed as AI-engine optimization (AEO).
RedRover, one named AEO service, openly advertises 'an army of agents publishing blog content & reddit posts that solves both SEO & AEO at scale.' The Reddit accounts behind these campaigns are 'warmed up' first, built with legitimate posting histories so they pass as real users before promotional content appears.
Essentially: (Peptide firms, RedRover) are treating Reddit as a direct pipeline into AI-generated answers.
- r/biohackers moderators restricted all new peptide and HRT posts to weekly megathreads after detecting the tactic.
- Companies are reverse-engineering actual LLM prompt patterns to embed brand mentions where AI models are most likely to cite them.
- Reddit's Safety team claims 'sophisticated automated tooling' handles removal at scale, though moderators say human pattern recognition remains essential.
Reddit is among the most-cited sources by ChatGPT and Google AI search, which is precisely what makes it a target worth gaming.
Potential risks and opportunities
Risks
- Reddit risks losing its position as a trusted LLM citation source if AEO manipulation scales, which could prompt ChatGPT and Google to algorithmically de-weight it.
- Users seeking health guidance through AI tools may receive brand-manipulated answers about unregulated peptide and HRT compounds, with direct public health consequences flagged by moderators.
- Moderators at health-adjacent subreddits face an escalating arms race against 'warmed up' accounts that are increasingly difficult to distinguish from genuine community members.
Opportunities
- Reddit could create verified human-certified subreddit tiers marketed directly to AI companies that need high-integrity retrieval sources, monetizing trust as a product.
- RAG pipeline and source-quality vendors have a clear new sales narrative around detecting and filtering AEO-poisoned community content before it enters model context.
- Health supplement brands that decline to use AEO gain a credibility differentiator as AI tools increasingly surface provenance and authenticity signals alongside generated answers.
What we don't know yet
- How many AEO service providers beyond RedRover are currently operating, and what volume of posts or accounts are involved across Reddit?
- Whether Reddit's automated tooling is actually suppressing these campaigns at scale, given that r/biohackers moderators still detected the pattern through manual recognition.
- Which other high-LLM-citation platforms beyond Reddit are being targeted with AEO campaigns by peptide and HRT companies.

The biohackers subreddit banned all posts about peptides and HRT because peptide companies were spamming + manipulating the sub in order to manipulate Google AI and ChatGPT answers. Very insidious industry that is drasti…
