this guy who copy and pasted his post
My guess is he forgot he replied to that thread already, and did it again. It's a useless post, but copying your own post isn't plagiarism, and not a reason for an instant permban.
How can you forget you replied and post the exact same post? It's just pure lazy sig spam. Not much different than copying someone else's post really and if you see his feedback from yahoo it's not the first time he's done it (though he's deleted that post). If you go through his posting history you'll likely find more but they're all one/two liner shitposts anyway so I don't think he deserves any mercy here.
