I wasn't able to witness Sushi's message so I can't comment on what he said, but I did see him get banned.
I was on however less than five minutes ago, playing under the name John_Cooper when an individual called John_Cena was administrating the server and I can say, I have no idea who gave him adminship, but whoever did make a horrible mistake that needs rectifying.
This John_Cena individual sees fit to enforce his odd will on the population of the server through acts such as;
-Disrupting the gameplay of battle-mode by constantly changing the map, forcing people to go certain units dubbing the action "rp".
-Using administrative chat for every single message he makes including general chit-chat.
-Forcing battle rounds to last longer when he's the last one alive by typing a message along the lines of "DUEL!!!!" in admin chat, so everyone else can wait longer before the round is over, because nobody dares question him.
-Along with banning people for any insult against him, his general character seems unable to deal with any sort of criticism, constructive or otherwise.
He is mentally unfit, immature, unethical in his administrating and an incredibly bad choice for the role which is quite clearly highlighted by his unprofessionalism.
I hope whoever gave him adminship looks over the logs at his performance and revokes his adminship for the good of the community.
