Ok so they trace the domain purchase to some drug addict in Russia who got offered $100 to buy it. Then what? Wait for them to leave the country then nab them? They will be waiting a long time.

If you had a way to pay them I'm sure some someone in a poor country would take the offer. Pretty sure that's how this goes down.

They don't really risk anything cause they can just leave the angry emails about piracy on read.
