Wikipedia

[Phorce]

This kind of thing could be taken through the Wikipedia appeals procedure. Look it up and look at a few historical cases. Winning is never guaranteed but there are cases where edit wars have been resolved even by compromise or edits being allowed in. Even "losing" is something as it gets some kind of resolution and a lot can be learned from what the positions of various editors are (rather than guessing from their various edits). It's better to do this in a group - an editing group can at least discuss approach, verify Wikipedia procedures and provide moral support.
