Locking thread due to lack of evidence. One teamhit that ends up being a kill isn't enough to justify a ban. Ban requests need compelling proof to show intent & evidence of teamwounding. If there were multiple repeated attacks or you had multiple screenshots of Admiral_Ballsack hitting you within a short period of time would be compelling evidence, and a ban or warning would be justified.
This is now the second ban request you have against an MB member this morning, and it's clear there is bad blood between you guys. If you don't watch it (and that goes to MB members as well as Goliathz) it's going to end in bantime. Personally I suggest an hour break.
These boards aren't for personal vendettas between different people. If you have a problem with someone in game report them via 'i' chat and an in-game admin will take a look. If that doesn't work, THEN go to the forums, and make sure you have enough proof. Crappy requests like this one only reduce your credibility.
TLDR stop shitting up these boards, and that goes for everyone involved.
