Good news! You can buy Murder Harem: Furry’s Vore Safari Edition (if that’s what you’re into) on Steam and nobody would ever know as long as you mark it as private while it’s in your basket! Assuming it works as they say you’ll still be able to play the game as normal but nobody else would know unless they directly log in to your account.
The faq doesn’t mention the new Steam Family stuff though. I’m guessing it’ll at least be hidden for parent accounts, but since parent accounts can control game access for child accounts that might not be as private?
What you’re describing there is called model collapse and it’s not a good thing. A generative AI ouroboros accumulates error until its output is useless.
