It's an old problem: https://gizmodo.com/british-cops-want-to-use-ai-to-spot-porn...

I've been fairly convinced a lot of social media bans, where people are genuinely confused about the bans, are just automatic moderation problems.

It's for detecting porn? I genuinely don't get it. I regularly post actual nudes on discord and never so much as a warning, crazy that a chessboard or grids are doing it. I wonder what makes an algorithm view a grid pattern as pornographic.

Somebody said people were posting images of QR codes that contained (links to?) CSAM. But instead of using a QR code decoder, it sounds like Discord used perceptual hashing or AI to detect and ban all QR-like images.

Ohhh that makes a lot more sense. Well, their implementation doesn't, but it makes sense that grids were mistaken for QR codes.
