Ostrakon was the name of the procedure for removing the rank of citizen. This procedure fell into disuse, but was partially re-implemented following an amendment and later incorporated into the Curial Overhaul 66. Citizen referrals may now be posted either privately to be judged by the Praefects, or publically as an Ostrakon, where all Citizen hold a vote.
List of ostracized members as of 2007 was:
- Agronak gro-Malog - (banned due to age restriction imposed by COPPA rules)
- Atheist Peace
- Ó Cathasaigh
The List of Citizens shows members that have had their citizenship revoked by Ostrakon or other means.
