First, this may be in the wrong forum.
Second, I'm not a mod writing type person, but in the battle results screen I would suggest that a fancy mod writing person create a mod that does two things (if possible)
Puts an icon next to the name of a person who played the game with the anonymizer turned on
Puts the user's real name in parenthesis next to their anonymized name. Currently in the battle results you can click on any name and view the user's real profile, so this should be feasible.
Call it the "Unanonymizer" or something.
Edit: After hitting submit I went and looked and saw there's a suggested mod forum... so if someone wants to delete this I'll repost it over there.
Edit 2: Apparently aslain is quick to move things... :D
