It's fantastic to get a response on this subject from the horse's mouth!
The problem is, as I'm sure rej is aware, that these notams actually reduce safety by increasing the clutter content to the point where other, more relevant, notams can be overlooked. This is especially true if one attempts to print a narrow route briefing for use in the cockpit, where one two pages become six or more!
Something that's puzzling is why these Notams don't have a radius of action based on their actual location, as others do. This would entirely avoid the problem, even if the radius was 1000 miles!
Anyway it's good to hear it's being taken seriously as a problem. Let's hope we don't get too many infringements as a result of Notam clutter in the meantime!
