You know, it occurs to me that you could be outing someone's real name. Even if people don't change from the automatic UserName to one that they come up with, there's nothing wrong with keeping one's real name out of this site.
It's the fact that the person is using the same exact picture on several different sites. Why is there a need for using the same pic, when an original pic is more "unique" and might not be identified by Google Lens?
