Since the user has publicly thanked for the warning and promised not to repeat the same mistake, and he still does - I don't think he understands what plagiarism is, there is no other explanation. It seems that I will also join those who will report his posts, because it is really not clear to me that there is still no penalty for and more than an obvious violation of the rules.
That would be a logical conclusion given his behavior and ignoring the warnings, but based on his post history somehow I think that he is perfectly aware of what he is doing. In the last month or so since he registered, he created more than 20 topics and you will agree that's quite a lot for a new forum member. My guess is that this is just an older user trying to farm the merit and somehow get to signature campaign once he reaches at least Member rank.
So far he had more luck than brain to avoid ban for plagiarism, but I hope that changes soon and he gets what he deserved weeks ago.
