Usage: ban [<all | new | select>
These commands prevent anyone from a site with a hostname containing the site substring from logging in to the game. You may ban a site to ALL, NEW or SELECT players. Banning a site to NEW players prevents any new players from registering. Banning a site to ALL players disallows ANY connections from that site. Banning a site SELECTively allows only players with site-ok flags to log in from that site. Ban with no argument returns a list of currently banned sites.
Unban removes the ban.
Examples:
ban all whitehouse.gov unban ai.mit.edu
