$5 isn't much. Why not post here a picture and 3d scan of your face as a token of good will?

It could help some start-ups that need such a face for demo purposes or other experiments.

I think most people, Including me, trust google/fb more than random people on hn.

Giving up your HN privacy is different than selling a scan of your face that anyone can already find with a simple Google search on Facebook or Linkedin.
