I have a feeling that the ad disapproval they got was done by a bot/photo image recognition software, not a real person representing Facebook. That’s a standard, generic response and if a real person were rejecting images, then they’d surely have received a real response to why the image was removed, not a standardized message that said stuff about “zombies and vampires”. Also, this was for an ad, not just a picture or video someone posted to their own account. So everyone complaining about seeing horrific things on FB opposed to this image being rejected - they are two different issues. One is users posting inappropriate content, and one is a computer program misidentifying a photo as inappropriate.
