Why do some people on the Internet use just a blank profile pic?

I don't know, it always makes me laugh. I'm not saying a person has to use a picture, it's just funny the way some people don't want to, or will use the generic pics like what GaG has. Like I have a co-worker who has a blank pic on his profile for the company messaging platform we use, and when I teased him about it he said "What do I need to use a picture for?" It just made me laugh.

For anyone else out there, why do you NOT use any picture for your avatar on an app/website?
