There is a huge wetlands directly behind my house. It is a very fun place to fly and do range checks. Drone often test flight here, I do not like this noisy voice. And it's not a joke that I'm worried about someone snooping on my privacy. Because I once saw a drone installed on the camera.
What you say does happen sometimes. I once saw in BBS a poor woman who was being photographed by a drone for a long time trying to find a solution. She was recommended to buy a jammer equipment. Then things settled down quickly.
One thing to note, though, is that it is best to buy non-gun jamming devices. Because it can save you a lot of time, you don't need to keep an eye out for drones.
