@jerry Because I've not seen the problem and really don't remember what was presented to me when I first joined this instance, so this may be an ignorant Q, but is there not a way for an instance to throw up a FAQ that specifies what it does and does not do to moderate/block/ban to anyone at the start of signup? A "fair warning, you're on your own here" alert?
@JamesWNeal the ability to do that without getting into the code is somewhat limited. Mastodon makes you agree to the rules of the server your signing up to, so that would be the best place to put such a thing, IMO
