This has gone on for a few years now at the Naruto Wiki and I've gotten fed up with this constant headbutting. This user, Cerez365 has been constantly reverting almost every single edit I make (he's notorious for doing it to others but targets me the most) he doesn't seem worthy, important or without other people's opinions/say in the matter (no one else has any problems with what I add), and partaking in every discussion I start or participate in solely to disagree with me. He would also completely revise my edits in his own way, at times using unneeded sophisticated wordings. In most of these fights I've handled them wrongly with the wrong behavior but I have to decided to not pick fights with or even talk to him anymore after the last big argument where we were warned by an mod. After that he started attaching this notification to his signature for a while that he is aware I am partaking in a discussion and intentionally spelled my username wrong to upset me. I pointed it out and he made a sarcastic apology to me. He hasn't been as bad as he used to be but he still continues to do it every once in a while. I have told the admins about him following my every edit and hoping they have him stay away from me and my edits but they never do anything about it. From what another user has said, he once followed him to another wiki to harass him about an argument they had at the Naruto Wiki. I've had it with this user basically harassing me and I am wondering what I should do about him.
EDIT: I have stated that I do not partake in the fights, however, I fail to control myself and another argument broke out. Again, I am not being mature about this but however, he acts as he is the mature one in this situation by insulting me, calling me grandma and stupid old teacher in Japanese. He is no better than me right now, provoking fights. He says he doesn't "intend to go after my throat" but he insists on continuing this when I've stopped this. He also said that he will in a way "fight back" if I respond in an agressive way (which wasn't even in an insulting way). But if he is the mature one that he thinks he is, he wouldn't even continue this no? Right now, he's probably tracking this discussion now to twist things around. I've said he follows my edits, and he's probably doing it now, which would prove my point about him following me around to infuriate me.
