When a biographical article about more than one person (multiple subjects) has incoming redirects from the names of its subjects, monitoring those redirects is necessary for compliance with Wikipedia's policy on biographies of living persons. This rcat accomplishes that purpose by sorting all redirected subjects of joint biographies to a maintenance category.
