+## Content requiring prior approval
+Certain types of changes may require prior approval from maintainers. This currently includes:
+
+* Code adding, removing, or updating the availability of alien races/species/human mutants. This includes pull requests attempting to add or remove features from said races/species/mutants. (Requires approval from at least one maintainer)
+* Code adding, removing, or modifying the functionality of adult-oriented features (such as, but not limited to: vore, genitals, MKUltra, and more). This also includes pull requests attempting to add or remove these features outright. (Requires approval from at least half of the formal maintainer team)
+
+If a PR contains any of the above content, and it lacks prior approval, then it may closed at maintainer discretion. Prior approval requires an @Maintainer ping in a relevant development/code or staff channel on the Discord. This is primarily to limit the impact of PRs that're created in bad faith, or are otherwise counterproductive to the server's health.
