Have you considered that mom or dad may in fact themselves have been the user on their kid's PC looking at porn, thinking that their spouse won't look there if they're checking on their spouse?
Yes, I have considered that.
But if your right on that, then when both parents are told, you should be able to see some concern on one or the others face.
If mom or dad is using the pc in the 10 year old girls bedroom to look at porn, the problem is worse than even I am suggesting don’t you think?
I am sure you are correct in some cases. But I know, when the kid has the pc password protected on their own login, that the Porn on their login is their own. Especially when the parents have to ask the kid for the password, so I can do my job.
If you don’t believe porn is targeting kids of 10 to 13 years old actively these days, well I am sorry to say you have your head in the sand.
