The Delegation of the Beatmap Approval Deciding Authorities; Submission Squad (BADASS) was the first forum-based selection method for new Beatmap Appreciation Team (BAT) members. New members were previously added through informal votes in the game's
#bat IRC channel, which did not receive enough visibility.
When selecting new members, a group of leaders would select candidates and the remaining BAT would provide their opinions. Any users who received approval from at minimum 3 BAT members and the BAT manager with no disapproval from anyone would be promoted to the team.
Until the manual trial of modding v2 in 2014, all BAT promotion methods used similar ideas to the Delegation of the BADASS.
