As far as I'm aware, Ethan has broken no rules. It's clear that he isn't who or what he claims to be, but there is no rule that we must be open and honest about ourselves. The mods could exercise yheir authority, but the use of power sets a precedent. It may be for the best that they do nothing. Being a self righteous prick isn't against the rules, so I don't think there's anything the mods can do. Shame they let him back after that one time...
