Well a long time a go, someone set the standard that civilian Aircraft registration numbers were public. Probably after the first pilot buzzed his girlfriends house.

You or I can't change that.
Before the internet, you had to ask the FAA to look up and N number, so that created a barrier to entry.
Now its easy to do.
The FAA decided that the things we do are AIRCRAFT, with a registration number, and aircraft registrations are public.
HISTORYWhen powered parachutes and ultra lights came into favor. Groups like EAA ( and their membership!) got out in front of it, added to the community based system of controls.
there were a lot of accidents, deaths and big problems. EAA really pressured operators and manufactures to behave or be regulated.
Initially the members were not happy. I remember a lot of EAA's saying that powered hang glider would ruin home building and experimental aircraft.
Members ( warbird guys, acro guys, home built guys) wanted them out of EAA but EAA put the screws to chapters and all to bring the ultralight guys on board.
EAA lobbied FAA, and manufactures to fix this problem, add rules that make sense.
And they did it they provided leadership to solve the problem.
Ultra lights do not need registration, training or a medical. Today there is less governmental scrutiny on a man carrying ultra light than a RC airplane.
TodayThe AMA tried to do a very similar thing here. They failed at the leadership level, we failed as well, the AMA could not put the screws to its membership to accept the drone guys.
So if you are upset about the current situation look in the mirror. Rather than bring them ( the quad guys) along, we all bitched and didn't lead, didn't provide a solution. They went off on their own and went nuts, Now we have this crap fest.
Imagine if the AMA has 10000 instructors, tech advisers and mentors? Not 180000 angry old men? We could have added a new branch, brought in new members to this hobby and staved off regulation.
I am not happy about this either, but early on I realized that these are forces beyond my control, and complaining isn't going to stop it. Change happens.
Oh at the end of the day, I will bet this will be a pain in the ass but not the end of the world as predicted.
