First off! I am not coming in to flame anyone!! I have just seen clans around forever that have this "No Cursing" policy.
If your answer is "It's just our way" or "Because we say so!" then dont bother with a response. like i said I am not trying to flame anyone. I am just looking for a valid reason to why this would be a "rule" in a counter strike server.
Counter Strike: Source is a game filled with decently intense graphic violence; Guns, Explosives and knife fights. The game is already rated Mature by the ESRB for blood and Intense Violence. ESRB's "Mature" rating means it is not recommended for person(s) under the age of seventeen. As you can see here that rating includes strong language (cursing).
MATURE: Titles rated M (Mature) have content that may be suitable for persons ages 17 and older. Titles in this category may contain intense violence, blood and gore, sexual content and/or strong language.
I am not here to tell you what you can or can't do with your clan. [Of course] I simple want to see the reasoning behind your decision to ban foul language in your severs.
(as a side note) Many great and highly intelligent people from our history have used the colorful language of cursing. "Heck" even the french had made it into an art form!
