My profile pic is something that represents me, I'm blonde and my fiancé calls me his "Baby Doll" sometimes. So I found a blonde doll pic to represent me.
I didn't use my face because I was on another site and used my own picture, within a short time the predators and creepers came out of the woodwork. It got so bad that I just closed my account and moved on, I was afraid that might happen here and used the pic I have up now.
Uh, it's my face and currently profile picture on fb. And show off? I guess they want to express themselves or just show their face. I didn't really give too much thought about my picture to be honest.
Mine is a quote and the man who spoke it. Very meaningful to me, and seems fitting for this site especially. I don't post my face because I appreciate the anonymity of this site. I don't want anybody to recognize me from the real world. I share stuff on here that nobody knows about me, and I shall keep it that way.
