I heard about this happing at first in Singapore. As I started researching these reports I found this is very common allover the world. This is how it tends to go down. A man meets woman online (sometimes a man pretending to be a women). They start talking and evolving their relationship till she strips for him. In return she wants him to strip also. This is when it takes a turn unexpected. Finally she tell him if he don't pay up, she will circulate the video she just filmed of him stripping. Getting naked and dancing isn't the worst thing to happen so I don't know what the big deal is (my normal Saturday night) but for some guys it's crushing.
