is it possible to compile a list of members most often plagiarized? I guess that would give us a damn good and unbiased metric of how valuable someone's posts are
Based on some of the copy/paste cases I've seen... the quality of what was being copied wasn't particularly good or "valuable". In a lot of cases it looked like "pick a random post (or posts) from a few posts/pages earlier -> Ctrl+C -> Ctrl+V".
So, I doubt this metric will be as useful as you think.
