XF 1.2 user profile url

There is ambiguity with user names. For example:

If my username was Jeremy Dentel, and someone else registered with jeremy-dentel, how would you distinguish the user profiles? Since the URLs should be:
http://xenforo.com/community/members/jeremy-dentel.81/ and http://xenforo.com/community/members/jeremy-dentel.521/ .
Only paid minecraft users can join my forums and you can only register that name once.
I would pay s0meone to make a private add-on for me so this would work.
