I posted this on the General Forum, but it might get lost, so I'll post here too:
I think the profanity filters are too far "upstream". To keep most people happy, I strongly suggest placing the filter closer to the listener's end. I.e. place it on the FE for incoming messages (rather than the host).
If someone doesn't want to hear profanity, they can activate the filter, and it mutes INCOMING messages, rather than the host filtering transmissions and smacking the speakers.
Further, because different users feel different words are more or less profane than others, it would be better if a keyword list be kept on the FE's rather than the host. This way, the "Damned Flaming-Ass" squad could fly and talk to each other without getting muted: they just delete "damned" and "ass" out of their lists (or just deactivate the filter altogether).
This is the best of both worlds: people can say what they want (they don't really care if anyone is listening); and those with senstive ears hear what they want.
