Who is hacker1001101001, this is a plagiarist,
Did he get banned for that and unbanned? That's news to me.
Anyway, OP presented some decent evidence and presented it well, which is why I merited the post. I don't know what hacker1001101001's past has to do with any of that. Either his arguments stand up or they don't, though I am curious now about what you've shown.
I think that fact that hacker1001101001 is / was banned for 60 days+2 year signature has nothing with this thread. Problem here is that one of allegedly accused users from OP (sergey1980) is saying something like :
"How can a plagiarist say anything about anything", and in this case to point finger in other user of this forum.
It is true that he plagiarized other user post, but from what is presented
here, he is not get perma-ban, but instant 60 days +2 years ban.
I agree with The Pharmacist that OP is presented decent evidence, but any accused member is have chance to defend himself, although I admit that this is not the case with banned members (they can only post in Meta).
