I suppose I have to respond now.
I don’t know, that’s why I proposed making a list. Why would mere looking at, or I as I understand it SEEING, something online be considered criminal?
Because “seeing” a crime and doing nothing to stop/prevent it, or even worse, “enjoying” it, is being an accessory after the fact.
No non-evil person could see child pornography and not want to alert authorities about it. If any one were to “see” child porn on a regular basis, they are assisting the production of it by being a user, whether they pay money or not or download or not.
