I'd be shocked it there were no people who read NANOG and  
misunderstood or blatantly ignored some of it.

Unfortunately, that means they would ignore / misunderstand the OP's  
request.  But there is probably a small percentage clueless enough to  
have stale bogon filters, but just clueful enough to realize what the  
OP said might apply to them.  A very small percentage....


Switching topics only slightly: Nick, do you have any data on what  
parts of the 'Net you can and cannot reach?  Perhaps take a dump of  
route-views and ping some IPs in each ASN?  Shouldn't be hard to  
script, and might yield useful data - both to you and the rest of us.
