I was playing online a couple of days ago and got an invite to a sesion. the other player was using mods and shortly after I got booted and  banned from online play till the 29th, as I recieved 2 txts 1 saying banned to excesive use of grenade launcher, even though I was not and had not used a grenade launcher in quite a while.the other 1 saying I would be reinstated on the 29th. is this something done by treyarch or the other player?
