Not everyone processes things the same way as you and many people (children, poorly educated folk) don't necessarily have the self-awareness to make such decisions reliably. And we both know there are people who delight in propagating such material and causing discomfort to others. Perhaps consider that the problem is not as simple as it appears to you.

I dont think its a simple problem. It is one without an optimal solution. I just think the downsides of having the stuff around are preferable to having people ruining their mental health out of financial desperation.
I also believe that the reliability would go up with time, people are able to learn quite a lot.
