more over, what help is it? I'm of two minds really about this:
 1) it's handy to say: the router in elbonia is being 'bad'
 2) it's just as simple to say: 'your router with interface ip 1.2.3.4
is being bad'
     (or: "everything through 1.2.3.4 is forked... plstofixkthxbi!")

It's often cited as a headache to maintain the PTRs (not really,
automation ftw!) I think really it gets down to "how does it really
help?"

also folk watch this list (and others)...though certainly the proper
contact method is that which is in peeringdb.
