Behavior of this user similar with user icynote_original[1] which i reported few days ago[2]. And that post actually is plagiarized[3], although i can't report since it's already deleted.
There are services like ninjastic and Loyce.club. His post was preserved there, anyway. Isn't it possible to provide a link to the post from these archives as proof? And I also wanted to ask, is not the person who used similar to someone else's account name, imposter? I think they can even get banned on the forum for such a thing. No?
