No, I meant when the bounty manager did say that the proof of authentication post or something like that is needed to join the bounty I did write it, otherwise I didn't .
Do you have an alt account that got banned? That might be the reason as well. Most of your post history is just bounty stuff, and people don't get banned for that. I have no doubt one of the forum detectives or a mod will show up to tell you exactly why you got banned, but my guess is still plagiarism. Your PM would have said something different if it was for something other than spam or copy/pasting.
