There had to be some human involvement. Which means a *person* (from the PRS?) must have shopped in her store, and heard the radio (or her singing), and thought, "Hmmm...This is outrageous! I'll have to do something about this! I'll report her!"
So, initially, this began with a single idiot.
I can only assume that this idiot brought back his report, and more *people* at the PRS thought, "This is outrageous! We'll have to do something about this!". It was then escalated, which resulted in the initial order.
So, subsequently, this was perpetuated by more idiots.
Somehow, the phrase, "A person is smart. People are stupid.", doesn't seem to apply here.
