Prevent edge-case exploitation that allows execution of arbitrary fantasy commands.

An edge-case issue where you may be able to exploit the bot having op.
Should you be the one being tracked, you could insert a newline in your tweet, and follow it up for "!ban <someone>" to execute a fantasy command.
