Well, if your ISP doesn't allow ORBS probes, its netblocks get put in a
separate category from the known relays.  So if I, as a mail admin,
feel that I want to block open relays but *not* block belligerent ISPs
like yours -- I can do so.

The fact that some mail admins don't read the docs and honor *all* the
ORBS listings equally ... is not ORBS's fault.  ORBS is a tool that can
be abused like any other.  They choose to publish the fact that there
is no way of knowing if such-and-such a netblock has open relays
because such-and-such an ISP wishes to hide from ORBS, for whatever
reason.  I may wish to use this information to block mail, or I may
choose to block only *known* relays -- my choice.  I don't see why
people find this so upsetting.
