Moderators of the r/biohackers subreddit claim that peptide companies are spamming their forum to get AI chatbots to scrape their posts and change their answers
Peptide companies have been doing AI-engine optimization by spamming the biohackers subreddit to manipulate ChatGPT and Google.

Context & Ripple Effects
Related coverage shows a progression from moderators facing high-volume, AI-generated spam to campaigns that use model APIs to produce varied messages capable of evading conventional filters. The r/biohackers allegation applies that pattern to a new objective: influencing the material AI chatbots and search systems may ingest.
The claim matters because Google and ChatGPT are named as downstream answer surfaces, making community moderation a potential weak point in the information supply chain rather than only a forum-quality problem.
First-order effects
r/biohackers moderators must contend with posts they say are promotional content designed for downstream AI and search retrieval, increasing the burden of distinguishing genuine discussion from coordinated manipulation.
Peptide companies accused of the activity gain a potential channel to shape how their products or claims appear in chatbot and search responses if the content is indexed or scraped.
Second-order effects
Reddit communities and other public forums may need tighter anti-spam controls and stronger provenance signals, as removing visible promotional posts alone may not prevent their reuse in external systems.
Google and ChatGPT face added pressure to detect coordinated, low-quality forum content in retrieval, crawling, and ranking pipelines; spam defenses built for duplicate SEO pages may be insufficient against varied conversational posts.
Third-order effects
If forum seeding becomes a repeatable AI-optimization tactic, online communities could become contested inputs for answer engines, shifting moderation from local governance toward a broader data-integrity function.
The pattern points to an arms race in which generative tools lower the cost of producing distinct spam while platforms, forums, and AI providers develop source-quality and manipulation-detection controls; the effectiveness of those controls remains uncertain.
The trend: This is one instance of AI-answer optimization: marketers using scalable generated content to influence the public web material that search and chatbot systems turn into recommendations and answers.
“We see the rise of things like peptides, compounds that are becoming mainstream that don't have much regulation,” one of the moderators of the biohackers subreddit told me on a call. “But we're also seeing this alongside incredibly risky sourcing.”
“Given the health and self-experimentation nature of the subreddit, the moderator said that they were worried that a sketchy company will promote their product, and someone will use it and get hurt.” [embedded post]
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 drastically changing the internet — www.404media.co/companies-a…
this is in large part because google turned Search into such a shitty, god-awful experience that it had to pay reddit to feature answers much higher up in Search results after people were relentlessly appending the word “reddit” to their searches to find answers [embedded post]

“We're also seeing this alongside incredibly risky sourcing, teens posting about wanting to grow an extra few inches. And then we're seeing AI manipulation from vendors trying to promote these peptides,” the biohacking subreddit mod told @jasonkoebler.bsky.social. — www.404med…
This article is about bot accounts posting favorable claims about peptides and HRT to r/biohackers, in order to bias responses from GPT and other LLMs. — Last night I stumbled across multiple threads on r/science that appear to be doing exactly the same thing.
