So, let me get this straight:
2. Selling ads == money laundering.
3. He's not violating tax laws, yet the IRS is still involved.
4. Purchasing email services from a US provider somehow makes you subject to all laws of the United States?
You're really grasping at straws, here.
As for 1...I agree that his service enabled users of that service to infringe on the copyrights of US entities, but are those copyrights valid in Poland or Ukraine? Do the laws of those countries spell out the punishment for copyright infringement of foreign copyrights? Why isn't he being punished under the laws of either his country of citizenship or residency, then? Masterminding a bank robbery != running a torrent tracker. In that case, there's an actual law being violated in the country where the law exists. Running a website is hardly bank robbery.
