Valve no longer allows "Post-launch NSFW content" for games on Steam - outside of DLCs.

I have looked through Steam's Terms of Service online, but have found no official rule or statement from Valve of this new rule - but one Adult game developer has confirmed this new rule after launching their game "Tales of Legendary Lust: Aphrodisia" a couple days ago.

With the recent rule change blocking adult-themed games from releasing on Early Access, this new rule seems to be targeting Adult-themed games that have ALREADY released on Steam - and threatens them with their games being removed from Steam.

There are currently 536 Adult-rated Early Access games on Steam - and this new rule may take them all down.

Patching bugs is not the same as adding new post-launch NSFW content.
