I think it’s implausible that someone can become aware of 30 images which are miscategorised as A1 CSAM. How would this malicious entity discover them? What’s the likelihood that this random array of odd images could make it into a target‘s photo library?

And what’s the likelihood that a human reviewer will see these 30 odd images and press the “yep it’s CSAM” button?

More likely as soon as Apple’s human review sees these oddball images, they’re going to investigate, mark those hashes as invalid, then contact their upstream data supplier who will fix their data and now those implausible images are now useless.
