Note to admins and vandalism reporters: A system administrator at Lancaster University said that they will examine logs (their servers send XFF info) to find vandals. The Head of User Services has directly talked to some of the identified vandals, and they have promised not to vandalise Wikipedia anymore.
In addition to any vandalism warnings or blocks, please send an email to abuse AT lancaster.ac.uk (with "Wikipedia vandalism" as the subject) with the diff and they will find and discipline the individual. If you do not want to do this yourself, just ask me and I'll be happy to do it instead.
I can say from personal experience that taking the extra few seconds to do this will make a difference. Thanks, Deathphoenix ʕ 16:38, 7 February 2007 (UTC)
