Moderators can hide opinions and comments
Super moderators can also hide questions
Uber moderators can.. . well, do the exact same things as a super moderator, except they can also freeze accounts (which I've only ever done with spam bots, and they've been rare lately)
Admins can remove hidden questions/opinions/comments, they're like supergods on this site.0
