in the first screen you teamattack him back after he teamhits you.
doesn't look like you are all innocent here.
okay, this guy was banned less than a week ago for teamkilling and teamattacking and like 30 min ago on NA2, he started teamattacking me again. I guess he came for revenge or something. I tried to defend myself but he was in plate armor. The second screen is when he was attacking me while I was fighting enemy and finally got me killed. This guy needs a week long ban, those 24h on last ban didnt learn him a lesson at all.
You were in the right until you "tried to defend yourself". Unless you are asking for an equal punishment, I'm going to leave this as it is.
However I agree that this was likely in response to getting him banned. Next time screencap, post it, report it in game with 'i' and if the admin online kicks the player for doing it intentionally, we will review to determine whether an additional and more lengthy ban is required.
I would suggest the two of you run the opposite ways when you spawn.
