I'm trying to think if there's a way for fandom to help other online communities (e.g. political blogs, religious blogs, etc.) guard against malicious puppetry, which they may well be experiencing without knowing it. But I don't want to make it too easy for puppeteers to get started, either. On the other other hand, it looks as though the most extreme puppeteers managed to put together pretty similar bags of tricks without learning from each other.
I get the feeling that there's also a new DSM (psychiatric diagnostic manual) classification in this.
