How about badges for having "X" amount of friend requests rejected? 5, 10, 25.......and such and such.
I have a suggestion too. Badges for X amount of vg$ paid in ban fines. Yesterday I noticed that vg$ have their own tab on the profile page and viewed the first page of my transactions. Apparently you get fined 20 vg$ per day you have been banned for, so I lost quite some money over the course of the last several years.
