Yes, folk seem to be doing this kind of thing, as shocking and disgusting as
it seems.

The problem is not agreements.  The problem is, as Scott says, detecting
violation thereof is not easy.  But traceroute -g is your friend.

E.g. UUNET's peering policy seems to be far more liberal than the press
would have us believe.  [ undoubtedly some of these are valid UUNET peers. ]

I also think it may be time we refuse to peer with anyone who inhibits LSR,
as it seems that validation is now mandatory.  I think we should be sending
out a "LSR is mandatory" notice to our peers.  Comments?

Smaller peers.  A non-trivial few are doing seriously disgusting things
which are going to cost you a lot of pain and some cash.  There is little
incentive for larger folk to peer with smaller ones.  Hence, larger peers
will simply cut the smaller masses off rather than spending the resource to
differentiate the bad apples from the good.  Maybe you want to do something
about it.  And soon.

At this point my lunch was ruined, and I gave up.
