I posted the other information because I felt it within our power as a community to be able to contact the ISP the guy came through to complain, since his account was locked he has already registered and tried again to get in... I'm sure he will succeed at some point.
Anyhow, revealing information like this is bad for two reasons. 1) Someone in a fit of anger may drive up to this address and find himself in jail or shot. 2) This address is NOT 100% accurate and may be an innocent you are either calling on the phone or visiting.
Let the ISP track him down and deal with him. As these trouble makers lose their connections they will stop. I would expect this guy to have 3+ ways to get online or shell accounts across the country. When I wasn't such a good boy, I had in excess of 10-20 shell accounts ranging from well known companies (don't ask) to universities. That way if I ever wanted to cause trouble I would really have nothing to lose...
