Clearly the joy of running a clean network is not shared by all :-). Yes, it is a little bit of extra hassle having to update filters when your downstreams make change requests (including verification, e.t.c.). But when some of our upstreams make us go through this, I'm much happier they do than they if they didn't. Some are even asking us to "fax" documents of such requests; a little extreme, but okay, I'll bite :-). We do have some upstreams who are pretty lax about this. But we certainly are not, and as a result, are yet to put one of our customers or the Internet in jeopardy because we let one through the cracks. It's 2012, we really shouldn't be seeing this type of thing anymore, particularly after what happened in Pakistan. Mark.
