Well, lets see, from the affidavit...
RapGodFathers.com and RMX4U.com both had forum sections labeled "Bootlegs" and "Appz" with admin written descriptions stating they were for the posting of links to illegally shared content. So they were encouraging copy right violations.
Torrent-Finder.com appears to be entirely clear of any wrong doing based on what is in the affidavit. Every piece of "evidence" came from some other website and Torrent-Finder presented it as news without any editorial comment being noted.
Dajaz1.com and Onsmash.com are both run by idiots apparently. They (and the artists that leaked to them) forgot that when the RIAA handed those huge ass checks to the rappers the RIAA got the copyrights. Doesn't matter that Kayne West told them they could leak his stuff... he doesn't own the distribution rights to it any more.
I doubt DHS and ICE are going to get their asses handed to them for busting 2 sites that skirted the rules so closely they fell over the edge, and 2 sites that found out the hard way that artists who sign with RIAA members don't own their distribution rights anymore.
The Torrent-Finder.com situation seems to be the only one that has no basis.
