I know this threads been dead awhile but I did a study on some of the .jpg files that where labeled as naked teens, underage or child porn. I found that most of them where either naked grown woman, jokes images that showed a random picture that said ha ha you pervert on them or viruses. only 12 out of over 40 files had young naked teens in them most of which where the same pic but just labled different. and there where several pics of teens that had cloths on and where posted in a sexy way.
Oh and I got several files that when you clicked delete it wouldn't delete and had for options had only only open, preview, send to, open with and cut and copy Of cource I new they where a virus because when I viewed it with paintshop pro under thumbnails it had a blank image. So I clicked cut on the folder, then paste in anouther folder and then opened the folder but not the file again and saw it had this pic. I then exited the folder clicked cut then I pasted it into the deletion bin and clicked delete and it was gone.
