The domain he's sending from, I understand that Sony may have outsourced their copy write claims but have you looked at "their" website? it's a little blank for a copywrite claim company.

The records for the domain antipirates-in.com sounds to me more like somebody is trying to hide something, Not that I'm saying the privacy option is a bad thing.

Also the wording he was using in his original Email " including the powerful internationally functional ic3.gov" Since we are talking about India here the fbi have no jurisdiction. 

I think it's either somebody with a grudge against mp3khan.net or somebody is having a laugh !!

But if I'm wrong .........
