Hi . Well somebody was flying that drone over blyth pier .Maybe it was the port authority? Unless somebody knows differentVideoing and drones spying on people fishing..........Are you serious..?
A lot of piers are private land owned by port authorities so that makes it illegal to video, take pictures without the owners consent.
Its a very long path but education is the only real way forward. Unfortunately most of the people dumping rubbish are thick, that's why they do it.!
