My negative answer all are bogus. Most of forum torrents websites are running on the Vbulletin(For ex- exbii.com etc).Its look strange but its true.When the vbulletin don't have the problem with torrents ,why us? Some days before the same problem create with the iweb. A clients has complain.
SOPA ,PIPA ,DMCA etc are the control the Internet Legal Policy. But they also fails somewhere.
