I think this says a lot about society's ideals for women and the pressure to conform to them.
These women probably
would post the pictures elsewhere in a desperate bid for attention. I heard on the news a while back that a staggering number of young women consider fame to be a top priority in their lives, and think that taking their clothes off is an easy path to fame and fortune a la Jordan & co. Plus they see the attention women get from men in lad's mags (

) and try to outdo each other in the 'slut stakes'.
I wish more women would realise that sexiness can be achieved whilst still retaining your dignity, power and self-worth.
We've all got boobs - it's what you do with them that counts! ;-)
