You are welcome to use and even add to this list, on the understanding that you acknowledge this is NOT an official Wikipedia blacklist of any description. No such blacklist exists, nor should it.
If you find yourself on this list then don't worry. It means that I have been disturbed by something you have done and am watching you. If the behaviour ceases, then you come off my list. (And don't try and remove yourself, you know I'll simply undo it.)
64.192.12.xxx - Fart boy. Persistent and irritating.
213.122.236.xxx - has a nasty habit of deleting articles (an expression of disagreement?) There are ample avenues for expressing dissent, deletion is not one of them.
12.64.78.xxx - not a really bad offender, but worth checking up on. Has created some nonsense pages.
161.removed, - seems to insist that Catalonia should be regarded as an independent nation. Target pages include anything Spain related.
195.removed - using Wikipedia to create advertorials for some software product called "FAR". Then vandalising other people's pages.
D-Removed - seems to have confused Wikipedia with Napster
208.removed - "tosser" status removed
