This is for all the ones that are afraid of the RIAA:

The RIAA (Really Into Anal Abuse) is just a porn release group that is trying to get some good publicity by scaring people. If you ever get an email from them, they just probably want you to stop sharing all their porn.
If they threat you to confiscate your HD, they are probably after some new porn you downloaded and that they still don't have.
They also have a side-kick, the MPAA (Making Porn Available to All), with which they make some nasty porn movies and release them to the underground public.
Yes they are sickos, but if you don't sign any contracts with them, then you are safe.
