• The admins here have access to anyones IP address as soon as they login here, regardless of what nickname they are using. By using that number it's a fairly simple matter to determine if someone is 'cloning' themselves by comparing it to earlier logins.*

Cooler, I think it's not that easy. What about dynamic IPs? Each time I go online I get a new IP - how will you make sure that the person you're assuming to be a clone is really a clone and not someone who happens to have the same ISP and got the same IP as some other person before?
