What is the deal with faceless body part profile pics?

I focused in on the gut I had before I lost the weight to be where I'm at today. I still want to drop about 15 more pounds so when I see the picture of where I was at it gives me incentive to keep goin. One of the great things about life is everyone is different. Some like to see their face or let others see their face, others don't.

On the pics where the bodies are very very hot but no face, I always wonder if they are being honest...

we are all born with body hair, why is it gross? it's hair.

It feels horrible, looks horrible, and is very unfeminine. yuck! More power to those who go hairy, but expect to find me sitting across the room from your smelly pits lol

Even if you remove your pic they stay available on google for days, sometimes years, depending if the pic is completely gone from the site's cache or not and when google updates. NEVER post a pic of your face anywhere on the net unless you're happy for it to one day show up on google! Aside from the immediate implications, there is now technology available to enable just about anybody to identify "similar pictures" on google, and soon facial recognition will be freely available!

so I read through a little, but in my case, this picture I chose is my whole self but on the thumbnail it only shows the middle, I wish there was an option like Facebook to choose what you want your thumbnail to show.
