A listing is proposed with evidence, reviewed by two people and then active for twelve months, with a re-review two weeks before it ends. Anybody on the list can appeal; while an appeal runs, the listing is frozen. Entries of the ScammerAlert lists are taken over automatically without a review and shown only as a warning; Defendr never acts on them by itself, and a ban or kick a moderator chooses on the join card is that moderator's own case. They end when ScammerAlert withdraws or deletes the entry.
