OK, I can wait few days but I want alert you because I read your post to DIREKTOR in your talk: 

Yeah, well, okay. How about I say, "an editor who has been the subject of many ANI reports, and whose behavior has often been criticized in those reports"? Oh, or, "an editor who has been blocked edit warring numerous times"? My use of "problem-editor" was simply a short-hand for these points. I do not believe that I made any comments about your behavior in this particular instance, so my apologies if you felt I was impugning you on this specific issue. Qwyrxian (talk) 

now, after your apologies for expression "problem-editor", may you take a step against this behavior? Those IP's edits were not by me but that guy cited my user name in edit summary without justifiable reason! May I defend myself against personal attacks? Regards
