FBI has no jurisdiction in Australia, it's the fucking AFP .
There's only 200k members in MPGH, and why the fuck would the FBI be on a hacking site?
They can't arrest me over this without proof, me residing in the US and without knowing who I am and where I live.
NZ isn't even a continent
Still, if you even set foot in USA with your computer your fucked.
The FBI or MPAA is not really concerned with individual people downloading content. Torrenting mass amounts is usually the ISP's concern. The MPAA and FBI is far more concerned with going after the people that release the content. FXG, noir, IMAGiNE etc etc. Unless your IP happens to come up in a court case against a seize of a torrent site or something, than the worst that will happen is you will get your internet turned off.
there are rare exceptions though. But you are either the most unlucky person, or you were really going at it really hard for them to notice.
