My username is probably as close to my real name in terms of initials that I am comfortable with. I don't use social media (aside from Pinterest) and I don't put my pictures online either. I have been stalked before, and this was before social media, and it is the kinda thing that sticks with you, so I try not to put as much about me out there.. I think the closest I've even come to that was on my forum, where people have known me for years from my interactions with them.
But aside from that, my name and face, are not online.. and if I have anything to do with it, it never will be.. it is scary what you can do now with someone's pictures..
