Not sure what your problem is? Did you just move to Hawaii, and the national state obsession with Spam is driving you crazy? Are you somehow being flooded by messages through Roll20, asking to send money to royalty in far off nations? Or are your players, drawing stuff all over like a bunch of kindergartners? If it is the last one, just give them a starter or splash page. After every session put the player tab on that page and let them go nuts. If they are doing it in the middle of the game, you can send the offending player to the splash page as a time out or kick them from your game if it is too distracting or offensive.
