Several have reported this. Some have been able to pinpoint this to
the use of forwarders (that is, their ISP got blocked), some
haven't....  In which case they seem to be doing excessive lookups to
the volume they have, or.... Spamhaus simply is mistaken... And where
are you supposed to complain then...?:-)
