If the point is to block spam, then using ORBS results in a lot of false
positives since anyone with an open relay is listed regardless of whether
they are being used to propagate spam. If the point is to block open
relays (and let the users of systems which have open relays know so that
they can bug their admins to fix the problems) then ORBS is great.
Personally I submit open relays to both ORBS and radparkers as
appropriate.

I think the original poster's use of "legitimate" was in reference to
those false positives for catching spam rather than a characterization of
ORBS' policies.
