hmmm...thats interesting in X2 it no longer has an option to display the IP address. So I'm not sure how you would go about it now. Maybe you can ping the person's domain name once you get the ip for the domain that they are using then you can block it in the system admin/edit preferences screen.
the problem with this approach is you could accidently block out a lot of users that you didn't intend on.
