Judging by complaints I've seen on my dash and the state of my own "flagged post" notices, the algorithm has randomly decided to go through old Sims 2 posts (possibly other games as well) and flag things like kids doing homework and elderly married couples dancing as Mature. All of the posts I appealed today and yesterday were from 2017, and several of them were reblogs, which I had no mechanism to appeal.
So far these are all clearing quickly. If this has happened to you, I suggest putting a simple sentence like "These are gameplay photos about a rated T for Teen game" into your clipboard and hitting Ctl+V to fill out each appeal, only pointing out the obvious or being snarky if you have the energy. Judging from past performance, we may have to do this for a few days until the algorithm gets adjusted or moves on to pasture new. I suspect they added a new Artificial Stupid measure and are fielding hundreds of hallucinated explicit photos from all parts of the site.
Just think how delightful it would be if this were the most annoying thing happening in the world this week!
