Last year I would browse a misc section of a forum because the stuff on there was quite amusing, to say the least I saw jailbait, saw a pic of a naked person, people would post pics and say blah blah I have nudes and send the pics to people, the person looked like they were only a year older then me, but no age was ever specified. i assumed. and i would just randomly click on links posted by other users, and one of the links was a disabled honeypot to lure child predators, the link was disabled because the media had got a hold of it. I was 16 at the time and had ZERO intention of looking for underage pornography.
(note: this was not a shady forum, it was controlled and monitored constantly)
