During the IP check it brings up a list of accounts registered with that IP address. I would like to be able to select users (on this page) to clean up also. It saves us having to go to:
IP check -> membercard -> profile -> postings -> post -> spam -> delete -> repeat
I believe the link will be added to the member card when appropriate, at least. That said, you may still need to look at the posts made by shared-IP users, so the process may not be that much quicker in reality.
