Ah ok, that makes more sense.

Will you assign the same alias to the same user every time, e.g. http://en.wikipedia.org/wiki/Identicon? That'd allow some kind of reputation system, at the cost of making it even easier to de-anonymize users.

As of now, users do not have persistent identities. Depending on how Freeversation develops, we may eventually let users opt-in for such aliases.
