FAA has been under resourced for many years. I am sure there were lots of people at the airport who knew what was going on, anyone of whom could have phoned the FSDO. The aviation community has to take responsibility for reporting something so obviously haywire. Sadly rogue operators like this are putting the entire historic aircraft operating policy framework under intense scrutiny. The easy thing for the FAA to do is just shut everyone down. If that happens don't just blame the regulator, everyone who kept silent when they knew things were going off the rail owns a piece of it too....
