There is already a stickied thread about Ventrilo rules and the rated "R" rooms. Ironically, just above this thread in the forums. For your benefit, I've copied the rules over:
"Ventrilo Rules Clarification
There has been a lot of talk recently about the "R" rated rooms on Ventrilo. Although rules on Ventrilo have been traditionally more lax, recent issues require us to clarify our stance.
General Ventrilo Etiquette
* Unless otherwise specified, rooms in Ventrilo are to be considered PG-13. In other words, eGO server rules apply in unmarked rooms.
* Be nice to your fellow members. Friendly conversation is expected; heated arguments will be dealt with swiftly.
?R? Rated Rooms
* "R" rated rooms do not mean that "X" rated content is allowed.
* No excessive swearing. This means that you are not allowed to drop your favorite flavor of the ?F? bomb every 2 minutes.
* No racist, sexist, or other demeaning language. This should be obvious and no slack will be given to offenders.
* Minors are expected to avoid these rooms.
This policy is not open for debate."
