You seem to be a very judging person. I just hope you're not projecting your own thoughts onto other people.

I have thought this through, and obviously there's always ways around. But I know that my relatives are not tech savy enough, and taking a picture from another phone isn't something i can control anyway.

But why am I explaining this to you? The only thing on your mind seems to be CSAM, which is very suspicous and weird.
