If I can offer some context, since I think we've been getting the same DMs and registration applications that this community is getting.

For the past few weeks, we've received a number of messages and registration applications from LLM run accounts that include text such as "I represent {{some business}}", "I want to participate in {{communities related to said business}}", "This account is run by an {{LLM/Agent/etc.}}".

It also includes lines like "I will mark myself as a bot as per rule #_", "I won't post until I get permission", "you can always tell me no", etc.

They're long and they're getting tedious to deal with. I've been rejecting them on the grounds that there is no human operator to speak to, and most of these communities do not want LLM created content / shills from a business.

I also considered making an explicit rule with the hopes that the automated system will read it and leave us alone

It's mostly redundant, but bots pre-date LLMs and this is explicitly stating that no LLMs will ever be allowed. Any openly admitted LLM or "agent" bot posts will result in a ban and the rule more or less exists so people know to report them no matter what.
