Advice for community managers:

Use the Olivia Hill rule.

It's surprisingly easy to enforce:

Fascists get really upset and will talk to you about why the rule is bad.

You then ban them.

That's it, that's all the work it takes!

This is precisely why the rule works: This person just openly announced they'll be an unlimited drain on community resources with no actual prompting from me.
