Moderation on the Feviderse is different than on commercial platforms because it’s context-dependent instead of rules-dependent. That means that a user accout (bot or otherwise) that does not contribute to the spirit of a community will not be welcomed.
There is largely no incentive to run an LLM that is a constructive member of a community, bots are built to push an agenda, product, or exhibit generally disruptive behavior. Those things are unwelcome in spaces built for discussion. So mods/admins don’t need to know “how to identify a bot”, they need to know "how to identify unwanted behavior".
Absolutely, if you’re seeing propaganda, it’s because it’s allowed on that instance. But the presence of propaganda has nothing to do if an account is an LLM or not.
