I've always wondered

How much child porn is going to get you busted. For example let' say a guy looks at porn for 2-3 hours a day..legitimate porn, nothing illegal. And let's say he does this for 2-3 years straight. That is alot of porn on your system. Let's say during a clicking frenzy a pop-up happens (which for those of you that look up porn knows it's going to happen alot) and its of the kid variety. You immediately click it off and continue with your business. Is this going to get you busted?
