It seems edit-warring is back 

Long time no see. Unfortunetly, I am here once again to say user "Ninguém" is once again edit-warring my edits. Funny, I have been out of Wikipedia for some days (too busy) and while I was out, user "Ninguém" almost did not post anything in Wikipedia. Now that I am returning, the user seems to be once again active in Wikipedia. It's incredible how fast he is able to edit an article I have recnetly edited. In a few minutes, he's there posting or reverting something. When I am not posting in Wikipedia, he is not posting too. 

I think it's clear the other user follows my edits. It's also funny an user who claimed to not to be associate with Wikipedia, who seemed to be leaving the projective, is once again active (only because I am returning). With hundreds of articles in Wikipedia, it seems the other users is only interested in the articles I recently posted. This is really strange. I try to be far from the other user, but it's impossible because he follows me and spends hours a day checking my recent edits. Please, do something aboout. It cannot keep this way.
