A couple humble, minor suggestions!

Like wolf said, there has already been some discussion about your second point, but I can't remember what came out of it. However, you gave me a good idea: when a player is kicked, have a menu pop up with a message telling them that they were kicked and what the reason was. Being kicked can happen suddenly and the only thing it shows is one line of text in your console, which quickly disappears.
