Ban

A ban is when the Admins or Mods decide a certain user has broken the rules and needs to get punished for such. It can be from only a day, to three days, to a week, to permanint.

A ban does not remove the account, which is impossible to do. It does not remove the posts, or items the user has (made).

An IP ban is when a user's IP address will be banned from the site, and thus that computer will no longer be able to view it. This is rarely, if ever, done because the fact that there are unrelated computers which share the same IP.
