Mars, no one gets banned without a good reason. I don't mean to sound like a douche here but your really pushing buttons on Sandtrooper now so relax mate please! Though I know the war has been messy with TRIBE vs OE, I don't think Sand would exploit that nade bug on purpose (If your talking about the old bug where you can change weapons then SYNC so it looked like you were firing 10000 nades). I think that bugs mostly gone too!

Use
/ignore *NAME* to ignore someone for that session in game if someones bothering you, though I still need to make a /unignore and make it perm until removed, it is fine for now to just use /ignore if someones bothering you at that time.
And no, I'm not taking sides, I never do, just seeing it how it is. You seem very hyped up + posting in caps.
