            e.player:sendMessage("Watch your language!")
            e:cancel() -- the message is not sent

5. Audit Log That Sees Cancelled Actions

Runs last and also receives events that other handlers cancelled:

mc.on("block.break", function(e)
    local status = e.cancelled and "denied" or "ok"
    print(("%s broke %s at %d %d %d: %s"):format(e.player.name, e.block, e.pos.x, e.pos.y, e.pos.z, status))
end, { priority = "lowest", receiveCancelled = true })
