Yeah, this is where I am. I'm a .world person, and I honestly think the admins have been doing a good job generally. I'm not a real Discord person, but I joined theirs after it was recommended a few times. Like you, I think using it as a backup because of the ddos attacks taking them down so much is reasonable, but they should use c/announcements as the primary communication venue. Note that there are a number of people on it who really seem to be enjoying the real time chat, and some even using the voice chat option, so it seems to be serving some people, at least.

I also think they made a potentially understandable mistake on blocking these communities, which I said at length in that thread. I'm inclined to think one issue with the overall Lemmy paradigm is that we have a lot of hobbiests as admins - people who may not have much experience with that, who don't have legal teams, and who might be gun shy about any potential litigation. We can't expect any person who decides to run a Lemmy instance on their laptop to have much feel for what content they're liable for and what's completely safe, so stuff in the grey area is going to make some people squeamish.
