I know how annoying it is when someone team kills on purpose but if you retaliate in a way that breaks the rules & are reported then chances are you will be suspended.

Best to just report & block them

yeah i was also in the middle of playing 2k and just got signed out and i didnt know what i did wrong someone must have been on my account i have a perfect record and good reputation and ive never been banned before so if i did get banned maybe a temporary instead of a perma? i might have said “kys” to someone a few times but only out of pure anger because my teamate wasnt playing defence but I DID NOT MEAN it in anyway so if i offended someone im really sorry i did not mean to say it only out of pure anger of my teamate

random teamates are never fun, unless you find a good group that are just playing to play & have fun, you wind up with whiny people that complain about you bringing down the team, I know because ive been there many times lol..... im the bringer down of
teams

Dont think I have one. Too aggressive a player to get perfections. A few times ive been 1 kill away or on the 15 and then had one of my teamates kill me. Its the same group of people I play with all the time and they do it for a laugh. I'd be just as quick
to do it to them though.

My Console was also banned for no reason ive never even tried to mod a game ive never been mean to anybody to get a report against me all i do is play MW2 but i got on yesterday and I Was banned
