Abstract: Understanding identity requires understanding the communities to which we belong; virtual communities are increasingly relevant to our personal identity. While many point to alleged differences of behavior and presentation online, these are not as great as first appear; characteristics which encourage antisocial behavior online do so offline as well. Furthermore, while deception and alteration of identity are possible online, they are difficult to sustain and rooted in our understanding of physical identities. Thus while there is space between our physical and virtual representations, the two are not sharply separated. Anonymity is often used to argue for such a separation, however while there is sufficient anonymity to allow for deceptive portrayals online, it is harder to attain than most realize. I discuss ways of piercing anonymity online and possible future ramifications of our increasing ability to do so. Less anonymity will likely lead to greater responsibility for our online actions, but it also will diminish our ability to use virtual worlds for identity experimentation. Ultimately, I argue that virtual and physical identities are intertwined: our online identity is influenced by the physical world but can also shape who we are and who we become.
