You can set steam-games to hidden, right? Keep em off your account page. Then you need to copy it out of your steam-folder so it doesn't tell everyone anyway each time you boot the game.
Frankly, steam just needs an option to turn that shit off.
Or theres the simple option of just pirating it (come on, that's what 99% of the threads on the site are for, lets not pretend otherwise.) and then maybe dropping the dev some money on patreon if you want to balance your Karma.
That'd get you the uncensored version without having to go public with it. You'd need to hunt down patches individually though.
