Sure, but traffic control problems can still be caused (temporarily) by abuse of the frequency/protocol by those intending to cause disruption.
Can you tell me more about the fake signals? Who sends them? Why? How often?
I'm guessing this doesn't cause traffic control problems due to the no-fly zone over that area?
Probably is not causing traffic issues. With that said I'm sure a number of TLA's are looking into it already, so whoever did it has hopefully took a number of infosec steps not to get caught and questioned.
