I think that silence on Private Messages and rooms like #lobby, #multiplayer or #BanchoBot should be exclueded. Why? Because, when I don't exacly know why I has been silented I want to tock with moderator, but how I discovered today it is impossible. #lobby, #multiplayer and #BanchoBot are both useful and necessary for playing on multiplayer. When the player spamms on PMs, so then Moderator should silent him or her on PM and public rooms, but I think that on #multiplayer and #BanchoBot player must be silenced at last when it's necessary.
