Firstly you're lucky to still be playing the server after hacking, if I was the Admin in that situation you would've been immediately permanently banned without a second thought. Second, I promise you EMP isn't looking for reasons to ban you because he has far more important things to worry about than you. If I'm not mistaken you weren't banned only for that case of RDM, but also for not being cooperative in the situation and then RDMing EMP yet again.

If it were up to me, you wouldn't be playing the server again without a doubt.
