I added some coloring pages as a reward, and used the term “adult coloring pages” in keeping with the explosion of content of this name. There is absolutely nothing even rated PG about them - it’s pages of country names, flags, croissants, etc.
Patreon automatically flagged my page as containing adult content, and I haven’t received a single new Patron since. I’ve written to support asking for the flag to be removed of course, but no response yet.
Look at this entirely representative sample: https://www.patreon.com/posts/grande-personne-21058383
You can see that it’s perfectly safe for all audiences.
Please remove the flag asap, it’s back to school season, my best moment of the year.
