this guy who copy and pasted his post
My guess is he forgot he replied to that thread already, and did it again. It's a useless post, but copying your own post isn't plagiarism, and not a reason for an instant permban.
It still looks copied though. Even if he claims that he forgot that he has already replied to the thread, it seems odd that anyone could type another post that is almost exactly the same with the exact phrasing. The only plausible reason why he is doing is so that he could pad his post count.
