secondary user acting illegally on the net?

[williamthethird]

My step brother is a secondary user on my webtv.I became suspicious of him after I discovered charges on my credit card that I didn't make.I canceled my credit card. I also called my ISP and had his password deleted, and looked in his email box.
I found a link to a website that contained child pornography.I terminated his account, but I have concerns:

He had no ability to copy,print, or download any materials during this time, but what constitutes illegal activity in reguards to this?
Is the simple act of visiting a site that contains illegal materials in itself an illegal act?
What are my liabilities as the primary user?--bill

You raised some interesting questions that I had never thought about before, so I checked under Title 18.
At one point, the word "display" is used in reguards to obscene materials.
It's feasible that a court could rule that the simple act of "displaying" illegal materials on ones monitor is an illegal act.
I doubt that this type thing has ever been successfully prosecuted before, but it could very well be done.--seth
