Can you elaborate about unwritten rules? Most of the bans I've seen has been for pretty clear rules violations, there's some stuff which might fly on reddit (like xenophobia, sexism, racism, transphobia), that will catch a ban here. Having rules against bigotry actually getting enforced is probably a confusing occurrence for some redditors. Even people behaving hostile will generally only catch a temp ban to cool down, permanent bans are more for people who are being bigoted.

I have had plenty of issues with at least one of the admins, despite that I have yet to be censored for saying as much. The red-baiting disguised as legitimate concerns rubs me the wrong way though.
