These have no idea what they're doing and do not participate to forums/communities/etc thus are difficult to regulate.
Blaming it on the UAV community is actually also being ignorant. The actual community is literally spammed by posts about flying safe/where to fly/etc.
I think that a decent analogy to these drone pilots are laser-pointer owners pointing at airplanes. That's totally retarded, doesn't achieve anything exciting - it only risk other ppl's life with low chance of getting caught. Just like drones attempting to "film" 747's landing and the like.
