One issue with prosecuting illegal FPVers based on videos on YouTube is it has to be proved when the video was shot. A trick some illegal street racers use on YouTube is to wait until one day after the statute of limitations has passed to post their videos. In the case of the $182,000 FAA fine the guy was live-streaming, which put a time-stamp on the offense. His name is Mikey (54 years old) and there is an interview on the YouTube channel Geeksvana about it if you're interested in the details.

Edit: The FAA isn't going get blood from a turnip. To determine the appropriate fine the FAA had asked for the guy's last 10 years tax returns. Apparently he has no assets (after his wife left him over his drone habit).
