Valve has updated its rules regarding content that developers aren’t allowed to publish on Steam (as reported by Game*Spark [archive]). The “Rules and Guidelines” section of Steamworks Documentation now has an extra clause, and it suggests that publishers are required to comply with rules and standards set forth by various third parties involved in processing electronic payments. The rule seems to be predominantly related to adult content.
What you shouldn’t publish on Steam:
15. Content that may violate the rules and standards set forth by Steam’s payment processors and related card networks and banks, or internet network providers. In particular, certain kinds of adult only content.
Prior to the update, the list included 14 clauses, prohibiting things like hate speech, malware, sexual content depicting real people and any form of exploitation of children. The new 15th clause suggests that Steam may additionally have to crack down on specific types of adult content in response to the requirements of payment processors and banks. There are currently no specific examples of what this may entail.
Update (2025/07/15 at 18:30 JST): According to SteamDB [wayback], a large number of games has been removed from the platform in the past 16 hours. Judging rom the list, it appears “sex simulator” type games with keywords such as “incest” and “slavery” make up the majority. There are some confusing cases like the removal of the Ace Attorney-inspired investigation game Trails of Innocence, although this could be a coincidental deletion.
On a related note, various video game and manga hosting platforms in Japan have in recent years run into trouble with payment processors and credit card networks. Due to certain content on the platforms going against the (often undisclosed) rules and standards of third parties handling payments, the platforms ended up without support for credit card payment. This has led to loss of revenue and even the closure of platforms like Manga Library Z. It is possible that Steam’s new rule is a means to prevent such complications from arising, however, as the specific “rules and standards” of the payment processors are also unclear, publishers might need to be extra cautious with releasing their games on the platform.

In particular, this could lead to a stifling of games that are in any way non-conforming, particularly given the current climate of repression in Valve's home country, the USA. I know about the rule change thanks to Youtuber and self-described former game developer NoahFuel Gaming, who has posted on Bluesky about the potential fallout for projects the banks and financial corporations consider "adult" because they deviate from reactionary framings of sex and gender. As the Youtuber writes: "Queer content gets flagged as 'explicit' even when it's PG. A trans dev making a personal story? 'Too controversial.' A surreal queer VN? 'Sexualized.' Financial deplatforming in action."

"Yeah... this is something that looks innocuous at first glance but it's a trojan horse," another believes. "LGBTQ+ has a habit of being mysteriously flagged as 'adult only.'" On ResetEra, similar points are being shared, as one writes: "Today it's porn games, tomorrow any game with LGBTQ+ content because it ends up labelled as 'adult.'"

As spotted [archive] by TheGamer, this triggered a mini-purge according to the Steam Database, with many problematic games such as "Incest Tales", "Wolf on Rail", "Sex Village", "Slave of the Police Officer", and many more, being delisted from the storefront.
