1. When you use Spam cleaner it has a 'Spam Ip check' , I think this should also be available when you look at the "IP address information for profile" tool, to see if there are other users matching the ip. 2. A way to see their ip when they have not posted anything, currently the "IP address information for profile" does not show up unless they post something on their status (or going all the way to the admin and look up the user). There should be a way to check even if they haven't posted anything.
