Although someone can used their avatar to maybe represented themselves, but we are not willing to show our images here.
Other forum members can use their own identity images, resize these images and upload it to the forum as their avatars but I am sure with you that Satoshi Nakamoto never do this.
He is a person (assume as a person), with serious concern about privacy and doing this practice to reveal his true identity is not his favorite practice. Satoshi Nakamoto always uses Tor, theymos said.
