Worst Gaming Organization of the Week: Metagaming.co.uk

As I'm playing early in the morning, English servers are the only populated servers. I decide to jump on [Metagaming.co.uk] Trouble in Terrorist Town (87.117.217.159:27015) and I play for a few maps. I killed a traitor and then proceeded to shoot Stephanov for shooting me after warning him to back off. He did not back off and killed me. In spectator, many players called for my ban after defending myself against Stephanov. At the same time, the admins slayed and kicked a player for RDM, and then banned him for a reason you can see in the screenshot.

I can understand a slay for RDM, but a kick after the slay? And then a ban after that? And let's look at the ban reason: "You are not supposed to rejoin after a kick."

If a player is not supposed to rejoin after a kick, why does the ability to kick exist?
