What recourse when someone is griefing you?
In a casual breakthrough I wasn't playing the objective, but was sniping, trying to level up a sniper rifle.
As the game progressed, our team got stuck on one objective, and one of the players in my squad started "griefing" me, by standing in front of me, stopping me from playing the game, because I wasn't playing like he wanted me to. I'm leveling up a sniper rifle in a bot lobby. I'm not sitting in a tank to have a high score, to make myself feel better about myself.
As this clown kept sitting in front of me, throwing smoke and shooting rockets at me, purposely giving away my position, I said "You're an idiot". He reported me, and I got a warning for "harassment and bullying". Really? Anyway, I put in an appeal, along with an explanation of exactly what happened, and it was denied.
What recourse do you have when someone purposely stops you from playing a game, your way?
