I appreciated reading your comment. Thanks for making it :)

What you’re worried about is basically what federation was built to stop.

If you don’t like the moderation of a community or other aspects, you or anyone else can make a new one on the same or a different instance, if you want.

You can even make it “private” (not federate) to keep others from coming in and recreating the problem you just fled.
