albert, you received the official PM about your ban plus two PMs from me. Between all of that, is was clearly explained to you what happened. I don't have the paddle verbage handy and can't access it from work, but here are the PMs:
I didn't see what he posted since I wasn't there at the time. I saw everyone chatting and came in and asked multiple times for everyone to stop. You purposely kept chatting in Callouts after my requests to stop. Everyone else stopped but you. Learn to listen to requests and you won't be banned.
this was his first offense as he's new, so yes he gets an official warning. you've gotten in trouble many times, so you're on a ban.
I understand you want to whine about this because it involves you, so of course you think it's unfair. But everything was done "by the book". Everytime you act up in chat, ignore mod requests, type racist comments, etc... you will earn an escalating ban. And if it continues, you'll permanently lose the privilege to use Chat.
Chat has a "punishment ladder" just like the forums: Warnings, Kicks, Bans (from 24 hours on up), Permaband.
