My personal view (and so not necessarily that of the Mods nor Admins...) is that there is enough diversity and richness in language (English and others...) to allow one's feelings, however strong, to be adequately expressed without resorting to vulgarity. Use, or worse still, over-use, of bad language diminishes my opinion of the author (that this matters little to them I'm quite aware, but still...). There are perhaps occasions when comic effect could, maybe, justify writing in that manner, but they are, I reckon, rather rare, and all the more effective by being so. It will be understood, then, that I am for keeping the profanity filter, hoping that it never need be invoked.
