I'm pretty sure I played that "I478" guy on BO2 League Play on my old tag "Ga5". He got in a lobby against me and was freaking out over my gamertag and stats. Myself and my three man party 6-0'd his three man party in SnD and at the end of the game when he was asking for me to add him, I told him that I don't add randoms. After that he probably sent me 30 messages asking for me to add him or 1v1 for an add, even though when I played him in league he got 6-0'd and went triple negative.
That's probably the most annoying thing about have an OG gamertag is whenever you play CoD or Halo there's always that one retard asking for you to add them or 1v1 them.
