The sad reality is that even if you get a legitimate IP, and the ISP is able to confirm that the address at the time links to Asik, law enforcement will still not be able to do anything because there's no PROOF of him committing a crime. After speaking with a few people, who are friends with some of his family members, they all seem to know about what he's doing.

What I propose, may not be legal, but it'll scare him off forever. It may be challenging though:

1. His family names are exposed, and along with that his family friends are also exposed. Some mutual friend will have enough information on the internet, such as their address.

2. Threaten to swat the mutual friend if they don't give up Asik's address. If they don't, swat them, until they do.

Once you have his address (he lives with his mom), it's over for him. Publish his address, and swat the swatter. You may think

that isn't going to do anything, you're wrong. He's too poor to move out, and his mother definitely won't put up with it.
