I have personally been trying to curb down on my swearing (something not at all helped by my feeble attempts at Dark Souls recently GOSH DANG IT) and I suppose that has also kept me from wanting to swear in character, if only because I just don't like to. I will emote that my characters swear but I prefer not to use any specific words if I can avoid it.
That said, I still think that the more colorful invocations of the Twelve (Thal's Balls! Mephnina's Tits! etc) are really funny.
