I also agree with you Jonathan, except that the photos of the black drongo nest and the TPK egretry were probably not submitted on this forum. Therefore these suggestions will not help in those situations.
This type of disturbance is a problem of eduction as you say. So let's educate people about proper use of playback and approaching nests without disturbing them too much. I think feeding wild birds is illegal so that should not be discussed or submitted here.
