Thanks for this. Perhaps invite only could work. When I signed up to my Lemmy instance, I was asked to say something nice about the UK to prove that I wasn’t a bot. I imagine this could work with a local quiz. But I personally favour the idea of it being open and communities being so small that it wouldn’t really benefit anyone to abuse. But it would certainly be nice to have the administration tools to quickly put a stop to it if it does occur. Something to think about. Thanks
