Doesn't matter if you don't remember. 
Doesn't matter if you don't usually plagiarize. 
Doesn't matter if you were new here and didn't read the rules and didn't have enough common sense. 
Doesn't matter if you're sorry. 
Doesn't matter if it was you only did it one time.

Get it?  All of those are excuses, and we've heard them all before.  You haven't made any extraordinary contributions to this forum, so there's no chance in hell you're going to get your account restored, unless it's with a signature ban or something.  I'm not sure what Theymos is doing with these appeals now, but my own opinion is that bitcointalk is better off without shitbags like you.  Good riddance.
