jacobhaney934, are you sure you are talking about the PDE?
(Are you a spammer? Just being a bit paranoid...)

You are not paranoid. It's just that these spammers are getting so inventive that they're much harder to track than the obvious download-movie-spam. I already deleted about 4 of jacobhaney934's threads. After each thread 'coincidently' another new first-post user responded to the thread with a 'useful link'. Interaction between multiple fake profiles, posing as helpful users with 'useful' links. Something very fishy going on here...

At the moment jacobhaney934's account is (against my better judgement) still unblocked for perhaps a last chance. Personally I don't believe this is a legit user. I mean this reply is bogus as seen on the actual screenshot above. I'll let you do the honors of throwing this one out (once you are convinced).
