You missed what I was saying. My point is that operating as a
network-hopping operation (by testing from addresses that the network
operator has not blocked) likens them to spammers sneaking around. A
firewall preventing the ORBS netblock from probing a particular range of
address space is an explicit statement that ORBS tests are unwelcome.
Why should the ORBS maintainers attempt to work around that very explicit
request from the network administrators to not probe their network? Their
most ethical and reasonable option is to add that address block manually
to the listing, because they cannot (without explicitly acting against the
wishes of that network's administration) verify that the addresses in that
space are relaying or not.
Let me make it simple for you: the firewall is a big red sign saying KEEP
OUT. ORBS is respecting that.

In your opinion. I see it as the only reasonable response for a system
that acts responsibly and consistantly on this point.

Blocking ORBS is an explicit request by the network administrator that
those probes are unwelcome. Hence, there's no other real option here,
without very clearly violating that request. The most I can see here would
be a single verification of a relay behind that netblock, just to be sure.

Yes, but the membership here would prefer you did, since we're rehashing
ancient arguments here yet again.

Hmm. I use it. Does that mean I have to unsubscribe from NANOG now?
