As the OP stated in another post "Well, the FAA has been caring about finding and fining folks around here. For flights that are over a year ago." Let's face it, FAA has stepped up its public awareness around drone safety and regulation enforcement greatly over the past year, and that's a good thing. I'm not aware of many $17,000 fines being slapped on recreational flyers from around 2018 for flying over a group at a picnic - the incidents that got publicity back then were for flying over a stadium full of people or some other truly egregious violation. Today is of course different, and the awareness campaigns the FAA has launched should have people convinced that they can't fly over people.
It's the part about ferreting out historic flights that worries me. Here's an example: shortly after I got my drone, I wanted to undertake a flight well within the 5-mile radius of an airport (remember, recreational flyers back then were regulated not by airspace, but by distance from airport). I called the tower as required, and the guy I talked to seemed confused as to why I was calling, and gave me the OK for the flight. It's highly doubtful he entered my request into any database, and today, with LAANC, I see that area is in a 0' grid - I'd never be approved for a flight there now. An FAA inspector viewing my video would rightfully be concerned about such a flight, but I only hope they would take into account the standards of the day vs. current standards. At the time I undertook the flight, I was following all regulations. By today's standards, I would have made a serious violation.
