Their job is to act on reports in the boards they are designated to, not to report in other boards.
For context, patrollers, can act on newbie accounts,
• Staffs, are limited to a specific board and only have moderator status in that board,
• Global mods can act anywhere on the forum, same with admins (although, all the ranks have different specifications of action).

Now if I'm a staff member, designated to the Bitcoin discussion board, I am not obligated to report posts outside my board, and those that do should be recognized, as it's an unpaid contribution.
