I got banned from chat once when I tried to type a message in binary. I got kicked, then when auto-connect kicked in, I got kicked by another bot, then when I got reconected I got kicked again. The third time I reconected, I said something like: "What just happened, I just said *binary*" which was stupid on my part, and the same thing happened, but this time I got auto-banned on the sixth reconnect. Luckily it was only temporary.
