I've never accepted any plagiarism. We discussed this quite a few times. Also, I spent money from my own pocket to hold a signature design contest. There is no point for me to accept plagiarism.
True, there is no point, but the fact is you did. It is only fair that you allow others to be "inspired" by your signature design and not post a scam accusation against the guy.
Let others judge whether tidus1097 was just inspired by my signature or it is indeed a copy. Both of us and tidus1097 may be biased.
