THE QUESTION IS-CAN A MODERATOR OF SOME MESSAGE BOARD DO SOME MANIPULATIONS WITH MY IP ADDRESS,CAN HE LOCATE ME,CAN HE REVEAL MY DATA?
They can ban the IP address you log in with, you can simply use a proxy server and log in again, they normally ban your user name along with your IP though.
Your IP only gives an approximate location to your home address, its pretty much useless to anyone, however the police can request your service provider to give your details if you are suspected of committing a crime.
