Help some guy says hes going to report me and says i will get banned for ever?

Ok so i was playing black ops on ps3 online and some guy said that lakers suck.(i have the lakers sign as my player card emblem) so i said no they dont and he just started talking about how mavericks eliminated them. So i left him alone. He got on the opposate team and i killed him around 7 times. He said he was reporting me for cheating because i kept on killing him amd for offensive emblem because he doesnt like lakers. Can i get banned from this?
