The "Signature" you enter into your forum profile, gets attached to every post you ever made.

If your signature contains a personal attack, name calling (with or without offensive language), or any other violation of the Forum Rules, we have no intention of expending the time and effort to move all your posts to an "opt-in" section where the rules are relaxed. Your signature will be edited.

If after a few instances, you are still too dense to take a hint, other more severe measures can be taken. Although the site owner has expressed some justifiable pride in how few members (other than professional spammers and trolls) have been banned, it's not completely off the table.
