Messaging apps like WhatsApp will save to your photo library though (unless disabled).

So any photo sent to you would be scanned. If you someone sent you a bunch of files, that might trigger a manual review, that would most likely flag your account.

I wouldn't expect that immediately deleting them would stop the review process.

again, I hope someone sends a couple of executives the recently posted images, to make a point

That is why they talk about having a manual review process. So that when someone wealthy or politically connected triggers the system there is a review.

I haven't used WhatsApp, but I'm tempted to call bullshit on that. I've never used any messaging app on iOS which saves photos to your photo library. Doing so would make no sense and would surely be infuriating. It's also worth noting that apps on iOS can't save to your photo library unless you give them explicit permission.

WhatsApp does by default save received images to your photo library (as opposed to e.g. iMessage). You can turn that off, though. And the permission to read from a user's photo library (to e.g. post images) includes the ability to write to it.

Gross. I can't fathom how anyone would put up with that.

WhatsApp really does it, by default. It's a weird choice.
