Forum:Blocking / Restricting Users

Just wondering what out procedure is for warning and blocking vandals? I draw your attention to Special:Contributions/194.83.12.5, while I would have put it down to random vandalism this is the third time from this IP address. It's also not just that he/she is doing it to current (and therefore) revertible articles, it's that they're creating new articles. --Tangerineduel 12:49, 2 May 2007 (UTC)
