And yes this!
I do know of some artists who engage in transgressive behaviour in the name of art, and I can't go too far due to outing potential. I know of them because I know people who have worked with them on other kinds of art (at which they are actually very good) and who knows a bit about their other stuff but actually doesn't want to know too much about it or tell me.
But you'll never know about it, it'll never be plastered on foyer walls or anywhere near children, it's a private consensual thing and kept that way.
And of course, they don't have to grift it out and flaunt it around because they have the skills to make other art that they get paid for, because they put the sodding work in.
