When viewing a deleted user as a moderator, we get the following information:

User was deleted on 4/26/2014 3:22:58 PM
User: user1234 (1234) (Account.Id=123456789) deleted by Madara Uchiha (27)
Reason: Reason for deletion
Mod flags: 42

Some deleted or destroyed users are bound to open new accounts to continue trolling/spamming etc. It would be nice if we could see a deleted user's last known IP address without having to remember to remembering it before we delete it.

I propose an additional line:

Last seen from IP: 123.123.123.123

Perhaps with a link to the mod's "Accounts with this IP" page.
