Actually, to quote the chat rules...
All people who state they are 'bored' will be instantly excused from chat to go write.
The punishment is not excessive. It's appropriate considering that chat is not just a hangout, someplace for you to waste your time. If you're on Miz, it's with the pretense that you're here to write. If you're bored, in chat, then go do something else. We simply just have no tolerance for people sitting in chat saying they are bored when there is SO MUCH else that you could be doing and being productive.
We don't have to give you a warning. That is also stated in the chat rules that you agreed too. I was the one that kicked you and Accolade actually DID give you a warning and you ignored it and simply kept asking why it wasn't okay that you said you were bored. You actually responded to the warning that was given to you, so I don't know why you're saying you didn't get one.
You were also told that you were excused for the evening. And you can ALWAYS write. If you're bored because you're waiting on a post from a thread partner, like you stated, then you can do a solo. Write a solo, plan a solo, anything. Start another thread with someone else. Develop your character more. Make plans for the future. Help develop a lore article. Help develop locations.... The list goes on and on.
As to your #4, as Gossamer says... You're in our house, you obey our rules. If you don't like the rules of chat, then don't be in chat. End of story.
