Hosting Hell
There are some people who will use an F9 OFF bot to crash down a server. This can be especially annoying when you are hosting an idle server, and you can't rehost until you get home from school.
A simple example:
(level: UHotel.j2l "Unknownfile's Hotel")
(Server: UF's Serv v1.23)
F9 F9 F9 OFF OFF OFF joined the game
F9 F9 F9 OFF OFF OFF left the game
F9 F9 F9 OFF OFF OFF joined the game
F9 F9 F9 OFF OFF OFF left the game
F9 F9 F9 OFF OFF OFF joined the game
F9 F9 F9 OFF OFF OFF left the game
F9 F9 F9 OFF OFF OFF joined the game
F9 F9 F9 OFF OFF OFF left the game
