I mean, at least implement a votekick or voteslay option or something it is greatly needed.
This made me smile. (I say smile because I don't laugh.)
Votekick and voteslay would both be very abused, and would recreate the situation you're in, with the complaint of "there aren't enough admins on" to deal with the votekick and voteslay abuse.
And a tip, when requesting forgiveness, don't try to excuse your actions by explaining how they RDMed first or something like that. It weakens the appeal.
And so this post will sound relatively on topic, I agree with the decision made. The ban is deserved, regardless of whether or not the bannee has had an epiphany or realized his mistakes or something.
But hey, at least he's honest.
