I wouldn't let my 19 year old daughter do this. Thankfully, she also has enough sense not to get herself involved in these type of situations.
The sad part was watching my baby lose a lot of friends that she's known since public school to a "party and have fun" lifestyle. Its a bit depressing watching kids you've known since they were in kindergarten drop out of school, get pregnant, and move in with a "boyfriend" before they hit 20.
The older I get, the more videos like this - and "teen" sites - upset me.
