I can't believe so many people find this a good idea. This is just plain dangerous and stupid.
First of all, the idea is stupid. You might want to d/l the files just to figure out what it is, to report it to the police in case it's real pedophilia for example. Or you might just be looking for plain porn, which is perfectly fine according to MY moral, and click accidentally on one file (or even download a bunch of them by selected these among others!).
Then, the implementation sucks big time. C'm'on!!! Some files are named youngass.jpg. HEL-LO?? How does this imply pedophilia? Tell me, is a 21 yo ass old? No, in my book it's a young ass, and lusting after 21 yo adults is nowhere close to pedophilia.
Same goes for schoolgirl.jpg, heck, I've had sex with a few high school girls in the not so distant past (I'm 27 now), and it was perfectly legal in my country, as they were over 15.
All in all, this is just another demagogue with noble and stupid intentions, probably a frustrated fundamentalist Xtian from the bible belt, where that kind of vigilantism is considered right. I'm still surprised that it gets so much support here.
Religion is for sheep.
