If you haven't caught a ban, you're probably a mostly cordial person who doesn't have to worry about it.
But in general, bans result from posting:
1) Nudity
2) Ad hominem arguments/name-calling (either towards other members or mods)
3) Console warring
4) Politics/Endorsing genocide (lol as if that needs to be something written down not to do)
5) Slurs
Otherwise, this place is pretty lenient. We get to cuss!
