Some pretty bad stuff out there.
The worst I saw was some website I stumbled across a few years ago, some dude in Europe who would basically ruin young european girls pussies - girls who needed the money really bad.
He would have these extremely long videos of slowly loosening a girl up until his fist was in half way to the elbow. Thats when it would get bad - he would start ragging on them telling them no man would want them now that they were so loose. Then he would get a BJ to completion from them, then piss all over their face.
By the end the girls were crying and I think one of them puked she was so upset.
