This excerpt was taken directly from Oliver0Olive's forum post :
"The ROBOT9000-BLEEDING chatroom is a bleeding-edge implementation of ROBOT9000.
In other words, you are muted for saying something that has already been said in that room.
At first, you will be muted for only 3 seconds. But each time you violate ROBOT9000's harsh regulations, that time will be multiplied by 3 (and it's cumulative).
This is slightly less strict than the ROBOT9000 standard as normally the mute time begins at 2 seconds but is multiplied by 4 for every violation.
Every day, (if I set up the task in MySQL correctly, anyway), the time will be decayed and divided by 2 - so you will eventually recover should you accumulate a massive penalty due to many violations.
Bear in mind this is just a bleeding-edge experiment, and your mute status inside the ROBOT9000-BLEEDING room does not make you banned, etc elsewhere on the site."
