Oh the e-mail address is simple enough you just need to apply for vip membership to get that I would assume and paypal will tell you who is requesting the payment, the same as they would with other transactions on your account. Reading comments elsewhere this site have suspended the VIP membership (until the heat dies down I would assume) . As for a campaign by the other side I would say that this isn't a campaign, it's an attempted defence by the free  sites to stop this moneygrabber expanding his empire, Dissent isn't allowed within his site from what I can make out, and vendors joining as VIP members to keep an eye out for their stuff would (if he gets his wish to kill these other sites ) be turfed out if they complained about their stuff being in there and their IP address blacklisted so they can't get back in. If you don't get in you can't know what is there to raise a DMCA. I am in no way defending the free sites, but if you can see your stuff you can request it's removal and if necessary DMCA the holding site.  From what I hear the owner of this site is claiming to be the copyright holder on stuff from here and daz and anywhere else that content is from that is in his VIP area in an attempt to keep it solely accessable by his members (exclusivity brings more paying members) and is sending DMCA notices to this effect to the file holding sites to get them taken down, once again making sure the files are held elsewhere for his members to access.  While this is great that he is curbing the piracy (in his own greed inspired way) I wouldn't be chuffed to find that a pirate is claiming copyright on MY works for his own greedy ends.
