I'd give it a few months before they scan every photo/video you ever take for other purposes. If you were at the wrong public gathering, I don't know if they'll even bother with parallel construction.
To stop the “production” you would need real time scanning of the camera when taking pictures and video and disable the ability to save if csam is detected.
- Saving, as before.
- Sharing, works, but due to a glitch the recipient got a blank blank image/video. He'll sure reply to let you know, but unfortunately incriminate himself in the process.
- Deleting, as before, no sorry, bugger, I/O error, can't delete this file. But support team has your address and is on their way.
