I had a similar experience a few weeks ago, also with a moron in an Atlanta.
I had asked "left or right ?", he said something along the lines of not asking stupid questions..
We were at either side of an island, our starting point, he sailed left around the island towards me, I was in a DD a couple of tiers below his Atlanta, and as soon as he had me in view, fired into my superstructure taking much of my health..
I asked him what that was for, he said "for asking stupid questions", I saw his guns were still pointing at me as he sailed past my right side, he fired again, missed me as he was too close.. so I stuck a volley of torps in his side just as he fired for a third time, sinking me.. my torps did their work perfectly and he also sank...
But we ruined the game for the rest of our team, and the chat box was rather full of slurs and anger for the rest of the game...
This moron then proceeded to send me hate messages for a few days, until I realized I could block him in my blacklist... I suspect if i had not blocked him, I would still be receiving messages...
I have his name, but will not mention it here unless asked. (Sadly, I was very new to the game, and did not know how to record then, but set up recording replays because of that incident.)
