I had a nice, long, well written post about this but my cookie expired as a I was typing and lost it all
Basically, getting together to fight this kind of piracy would surely be effective, but actually getting people in this business together is much tougher than it should be...this webmaster doesn't like that webmaster, etc.
I've gotten both Oron and Filepost to ban specific user accounts, make sure you keep track and point out repeat patterns in every DMCA. CC Paypal after they do not comply. It's like pulling teeth but it's worked for me.
Paypal is ridiculous overall. They will not process for us, but they will process for our content to be stolen? Must be hard times...
Eventually this will all fall like a house of cards. There is a clear paper-trail of significant money changing hands here, no doubt taxes not being paid either.
