Ask HN: Should we avoid posting our faces online?

Should we avoid posting our faces online?

I'm increasingly wary about making my actual face the chosen 'profile picture' in Gmail, Facebook, Meetup, Linkedin and such.

It's just creepy that someone could be running a crawler and build a scrapped database, mapping real names to faces. Perhaps someone did this already, owning tens of millions of records?

Although, I'm not sure of what actual evil stuff could be done with such a database.

I can think of:

- iPhone X Face ID. Simply a matter of not using it.

- Deepfakes. Arguably not a real concern unless you are a celebrity or someone remarkably attractive.

Anything else?
