No. By throwaway account I mean having a button that says "Generate a throwaway account for me", which then causes the back-end to generate a random hex string. The user then clicks on http://omgsmackdown.com/58d7875171f9b6a4c22d6b46e4da9b26 and may optionally associate a nickname with that identity, but from that point on, the user is logged in as far as the app is concerned.
