I have no way of verifying what these people are telling me, and I can’t help them even if I did. And even more than this: my first reaction is to wonder if they’re all actually pedophiles who are just lying to me, and/or if they’re going to text CSAM at me. (Because that’s the power of this accusation — nobody will trust you once they hear it.)
Some of these folks have had their lives ruined and some have told me they were hospitalized and considered suicide, even though they weren’t actually prosecuted. I can certainly imagine being in their situation due to the mistake of having an asshole friend-of-a-friend in a group chat and some bad settings in my phone. (I have neither, thankfully.)
If none of this stuff convinces you, here is a much more carefully-documented version of a similar story in which a dad took a photo of their toddler’s rash and was subsequently investigated for CSAM. This one has the “happy” ending that the accused is entirely cleared by the police, but never gets his Google account back and has to live with whatever other trauma and shame comes from the investigation: https://www.nytimes.com/2022/08/21/technology/google-surveil...
