Basically an admin puts a brick in their inventory, and "places" a ghost brick, and says something like /clearthisbrick, and all the bricks of that kind are cleared.
An application: Idiots keep using spawn points in fort wars, causing players to spawn in other players' bases.
Perhaps also a parameter that allows admins to only remove the bricks from non-admins, to remove the bricks and anything it is supporting, or perhaps the bricks alone, serving to preserve any supported bricks.
