Look guys, they never release demos, they never have done, anyone who's been banned for hacking with demo proof has never had the demos released. So stop barking up that tree.
However, the fact that HD's PR thread is sitting in dev\null is all the evidence you need to tell you this is a hoax.
Firstly, the PR forum is moderated, that means any post in there requires a forum admin to look over it and approve it before posting. There's no way in hell a 1 line "OMGZ I R HACK" post is going to be approved.
Next, as mentioned above, the replies and locking are near instant after it's posting, take a look at any other PR thread, this never happens.
Also notice how the thread was moved to dev\null after approval and locking. This is clear evidence of the thread existing and HD being banned, so why, exactly, is JHunz beat about the bush in the announcement post when anyone can easy just go to either dev\null or the PR forum and see the thread staring them in the face? Hell, why is there even an announcement about it, unless they actually want you to notice it, film at 11.
Finally, apparantly Vinnie has been accumulating evidence against HD for some time, guys, raise your hands if you've ever seen Vinnie ingame for over an hour in total, i know for one that in my year and a half being a reg here, i haven't.
Guys, get over it, it's a hoax, and a pretty obviously done one too.
