But don't you realise that you are actually filtering the words to phrases that are  worse than the profanities you are blocking? You are  just making it worse. I don't see how you aren't understanding that.

No, I don't think you understand. The words get filtered into a bunch of incoherent nonsense which as a result makes the person using profanity look relatively incompetent. This will hopefully reform these troubled individuals into capable people who are able to word their sentences better.

I don't think it is appropriate to, for example, use shit in place of what you are actually referring to. This use of shit causes your sentence to be relatively ambiguous for no good reason. This and a few other things common in the use of profanity makes you seem like you have no idea what you're talking about.
