By all means, verify the numbers, if that is what it takes to convince you.
I have been a computer repair tech for almost 10 years now, and I can’t remember how many times, I have caught 10 to 12 year old girls with hard core porn on their pc’s. If they are into to porn, They are readily at risk of sex slavery.
(Yes I tell parents about it, and its disturbing how many don’t care.)
My gut says the 100,000 number is actually most likely low.
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?
