Check out Fax Wars. Tom Martino (The TroubleShooter) of nationally syndicated radio fame has a network of attorneys who are actively pursuing these fax-spammers. You simply bundle your junk faxes together, sign-over the litigation rights and send them the faxes (snail mail). In return, for every paument they receive on your faxes, they return a portion of the settlement to you. So, you get paid, for doing nothing but collecting them.
