This is growing into a bigger problem.
I think it would be good if a people could pitch in and help Maximus Rex and others stay on top of this.
This user has at least 7 accounts and now seems to searching for articles to argue about -- and is adding NPOV headers and removing "incorrect" or "contested" information. E.g., http://en.wikipedia.org/w/wiki.phtml?title=Microsoft_antitrust_case&action=history
Here's the section at Vandalism in progress: http://en.wikipedia.org/wiki/Wikipedia:Vandalism_in_progress#User:Bird,User:Raptor_and_various_other_incarnations

A User who went by the name of Bird has gone on a vandalism rampage, blanking several articles he/she worked on, claiming that everything he included in Wikipedia was either made up or plaigarized. I'm wondering if someone got ahold of the user's account and is causing problems, or if this person has had this in mind from the time he/she first logged in. Regardless, it seems that the user claims that he will be issuing a "press release" pointing out how flawed Wikipedia is.
See [[User:David Newton/Bird Dispute]] for more detail.
