You where given a synth ban after a consistent history of gank, law lawyering, and powergaming as AI and borgs. The complaint you linked was apparently the last straw. You where given a perma server ban after ban dodging on alts and living to staff about it.
My problems are a few. You straight up admitted to metagrudging someone and then when you where synth banned for it you felt the ban was unfair...? I don't really understand the thought process.
