Because of changes in RFCs ipwhois was discontinued from rfc-ignorant end
of last year, there is a link to announcement about it on their website.

Completewhois took most of the data and incorporated it into our invalid
whois project database, you can use it for blocklisting as
Or in combination with bogons & hijacked lists:

Its not against any RFC and its not wrong. Its rather common trick used 
when previously public page is no longer public and website owner does
not want (or can not by order court, etc) maintain any info about it on 
its webiste, but removing its dns completely can not be done for some 

Whoever queries and sees will understand (including based
on the logs like you did) that resource is no longer available and
will hopefully not query for it any more. As you can understand this
is what they they want, because if they just removed ipwhois.rfc-ignorant
then you'd continue to get NXDOMAIN and will never know to stop
querying for it.
