Why are fake avatars a problem in the first place? Almost every website or program that allows avatars has fake ones. Do you want this site to become like Yahoo Answers and have stupid computer generated 2D avatars instead?
Most people here use some strange screen name - not using their real name. This is a type of social networking site - but dealing mostly with sex and it is still something not to discuss in public subject. Everybody might be using fake pictures and one can not find out the truth.
Why only profile picture? GAG can force to use real name and e-mail ID for membership. No fake screen names too. Why are you not using your real name or real picture here? There is something not good socially here - or people do not like to get identify by others. Many will not answer or ask anything here, and may not continue their membership.
I would like that! I am one of relatively few on the site that has a picture of my real self as my dp and who never answers anonymously. It would be interesting to see who people were/what they look like when they don't have the option of hiding.
