Seriously, what is the point of that? What possible satisfaction could you get from comments on a fic you didn't write? I've had people re-post my fics before, which, whilst annoying, at least credited me as author. But to steal it in its entirely, word for word? WTF?
(Incidentally, stylinsonnn, there's one of yours on there as well.)
Anyway, I left a message asking them to take it down, and also reported them to the site authorities, and it's been removed, I don't know which worked. One way or another...
PS, if you are KillPrinceCharming, and you're reading this? I hope you get worms.
