If the developers implement some kind of censoring system ingame, I hope they do it sensibly. Some games have such strict rules... like, you can\'t say \'damn\' for example... but then they miss other swearwords which are much much worse. Perhaps it would be better to include some rule in the TOS of the game which reminds players to keep their language clean, and leave it up to the GMs to kick people who repeatedly ignore this.
If the problem turns out to be frequent though, perhaps censoring would be a better, easier-to-handle option.
