I'd be interested in some project like that, but I'm afraid it would only 
get to a general area. With maybe 3-10 idiots at any one time, and the 3-10 
active at any time probably varying every hour, it might be pretty tough to 
do anything meaningful.

Since attention is what they want, I wonder if this effort would not 
encourage participation in jamming at a faster rate than it solves anything?

Has anyone ever looked to see if there is any correlation between 
intentional QRM and the DX station spreading people over a wide swath of the 
band? More than once, I've heard people intentionally threaten to QRM DX 
because they were POed that their QSO was interrupted by a pileup.
