I think you're wrong. I think it's the exact oposite. The more suposedly personal but professional porn pics posted the less likely we are willing to post pics of ourselves. It always very obvious what is profesionally produced porn and what is pictures taken at home. Off-course there's no guarante that home-made pics are genuine, but I don't think any of us would put any time into exposing pics of that nature.
Since you felt in necessary to warn me for this I haven't uploaded pics of myself. So there. The effects are immediate for some.
