Sending them an email with their ISP and an IP normally tells them you know who they are and they back off.

IP numbers can be disguised so that's no real way to threaten them.

You can block users with proxies but you might lose a lot of legit users.

You have to wait for them to make a mistake. They usually will because most times its just a kid with too much time on their hands.

Most spammers cover their tracks pretty well and a lot of them are not kids.

Rather than try to irritate them just block them so they don't come back.
