This is a direct quote from him on MSN when I asked for a MM, right before he blocked me - "naw i had a pro account in halo 3 with 50 on eveything expect two things with pros on halo 3 and the dude i was trading ask if we can use a mm and i sed yea and once i gave him the info he left"
I asked which account he had and he said Heinz from tD. He wouldn't tell me the gamertag though *rolls eyes* and he also said he's tD Bravo's brother (coach for tD) and that he is a pro in COD4 and plays for Fear.
My unprofessional opinion is do not trade. Just sayin'
