Interesting read on BBC today
External Link/Members OnlyGist of it is guy gets conned into skyping with what he thinks is a girl, but is in reality a recording of a girl. They get him to have a wank making sure he's showing his face at the same time and after the deed send him the video they took of him wanking threatening to send it to people unless he pays up.
I like the occasional bit of webcam sex (normally on aw or myfreecams) so I could have fallen for this scam if I hadn't read the article!
