This is where I'll have to draw the line: Acura3600 may have "slipped up" in some (actually many) copy&paste quotes, but I can say with confidence that I know my fellow German board members well enough to vouch for him/her (at least for posts on the German board, since I don't usually read the others very much).
Fair enough.
Being too harsh on someone like Acura will not help make bitcointalk a better place.
I don't think a signature ban is too harsh. And I think altcoin copy-pasta across multiple threads is not what this forum is for, regardless if we file it under plagiarism or not.
