Man the lack of mechanical understanding around here is stunning. Loose spokes will not affect the brake rotor unless it is a perimeter brake. Never saw one of those attached to a laced wheel either. The rotor is attached to the hub which is fixed in place by the clamping force of a tightened axle against the forks making it a rigid assembly. Sheesh..............
If you're going to be crazy,you have to get paid for it or you'll get locked up.
