Why Use Anything Else?I understand the users that would like to remain anonymous, but still want to show off a bit of their personality visually, it makes sense to use pictures that are not your own.
I do not, however, understand individuals that use pictures that are not their own, but claim them to be. It's as though they are so uncomfortable with their own bodies that they would rather risk being caught in a lie by potential friends than show people who they truly are. I think the best solution to this is to just not put pictures up of yourself if you're not comfortable with what you look like.
I have no issues with what I look like, really. Not out of arrogance, not out of vain, but purely that I have accepted that this is how I look. This is me. Take it or leave it.
Everyone has flaws, finding a perfect person on EP is most likely not going to happen, so you might as well just use your real photos.
