Hopefully one day you guys will “get the picture”. The more you gossip about high profile individuals and their flight activity, the more you will see being blocked. The main reason people use personal aircraft is for the element of privacy.
If you want to talk about the movement of celebs or other high profile people, do so privately. The more you discuss these individuals in public, the greater the liklihood is of them blocking their n-numbers.
John Travolta is a huge supporter of aviation and he kept all his tail numbers visible for a long time. His kid dies and all you can manage to do is broadcast to the world where his planes are going and how much noise he’s making at Greystone. Since you couldn’t show the guy a little respect and leave him alone, now he took away your ability to snoop.
