I've seen two or three vulgarity messages and declared every one of them vulgar. They all contained things that just seemed inconceivable for a noble to say, in a manner which would not be acceptable.
I generally think vulgarity is underused, not over-used.
Also, vulgarity is emphatically NOT an OOC language police feature. Hence why you can't flag OOC messages as vulgar. It's an IC tool for IC breaches of etiquette.
