Hey Another idea,

I know I've been on other online communities where its not uncommon for users to create fake accounts for the purpose of causing trouble or harassing another user.

I know there's a mod already in place for tracking the IPs of an user account, which if suspected, could be used to compare to the account causing trouble.

But if there's no idea who might have said or done something (due to the fake account) it'd be nice to be able to do a lookup of users connected to an IP and then message/deal with them accordingly.
