lol "shuting down the server" to look at the logs? maaan, get a clue, will you?
If have the server-browser, just do a "server-info" and viola, you have the IP.
Then do a whois on the IP et voila you have the Owner and hoster, heck even with his full address...
If someone can't be bothered to do that himself, he should be ignored.
btw that IS in the 101 of internet-usage...
So you go ahead and shut down your server just to get the IP and the addresses. roflols
