I suppose i don't see the point.
The reader knows what you censored either way, so by using the words and then censoring them you don't achieve your implied preference for reducing vulgarity in communication (so it might be more impactful and irregular when applied) at all.
Anyone who reads "forking shut" knows what you are writing there in reality. Kinda feels to me like putting on censored porn to make it family friendly, that's not working. Either watch a family movie, or some actual porn in private.
The only reasonable course of action would be to avoid vulgarity and those stand-ins for it completely in your communication.
