I can't agree more....
Firstly, the internet has made it possible for every self-important yellow-jacket-wearing tom dick and harry who wants to fly a kite, or everybody with a chimney over 5ft tall which has a defunct red light on it (but whose lawyers have told him he has a "duty of care"
) to feed their garbage into the system. This is why at least 90% of notams are total garbage.
Actually it is worse abroad than here. Do a briefing for a flight down to Greece, and you get all the Greek/Turkish disputes; pages of them. And on one flight I got many pages of notams all the way down Italy where some dick notamed every lamp-post along the Adriatic...
The more sinister thing is PPR and I suspect what has happened is that in the past the airport was simply open for traffic, and because they could not stop the traffic (and should not be able to, being a public airport) they had to make an effort. But today it is easy for the yellow-jacket **** to close it if a squashed hedgehog is reported on the runway. Why? Because the closure is very easy to notify to the whole world.
This is why I keep banging on
about contacting the airport. In the UK, and other reliably English speaking countries, it is just an easy phone call.
