Every time we see a troll banned (rightly so), the mod usually gives a list of their other user profiles. Most of the arseholes who are here to cause trouble have more than one profile, and they're invariably found out.

Why don't (and if not, why not?) mods/whoever check new profiles as they happen to make sure this isn't some troll setting himself up again? This might result in a delay to the new profile being accepted, but it might be worth it to the boards to keep us from having to suffer through their shite before banning.
