Have a backup instance in mind, if the culture of your current one doesn’t work out. Especially yours. People are not at liberty to express what’s what with this instance on this instance.

Do not be afraid to block people, because they will keep showing up, and some of them are psychic vampires whom their instances will never punish. Universal Monk has a sockpuppet on every instance and will probably respond rudely to slash angrily report this comment for pointing out they’re a block-evading ‘hmm curious’ spambot.

As on reddit, beware the cult of civility. Some communities (subs) will viciously punish ‘fuck off’ but not any behavior that frankly deserves a vulgar dismissal. Read the sidebar. Don’t be afraid to search for alternative communities if the sole moderator is intolerable. See also the Ye Power Trippin Bastards community on dbzer0.
