The Shared Account Mafia was a community ran event on Niconico in 2022 where 12 creators uploaded videos to a single shared account, where viewers then voted on who they believed created each video. Like the party game Mafia, participants tried to identify hidden identities, and creators scored higher when fewer people correctly identified them (i.e. they successfully "hid" their style). The event ran across four rounds ("nights"), with a final results livestream and a spreadsheet revealing all answers.
