It's also not effective in various situations.
The bad behavior is not disabling abused domains, it's the method used to do it
(by giving no answer instead of actively giving a negative answer).
When a http client asks recursive resolver A for an A RR, and no
response is received,
the client will then go to recursive resolver B and make the very
same query again,
and possibly on to recursive resolver C.
One of the secondary/tertiary recursive resolvers may hand the client
a cached response that had been obtained before the registrar took any
If instead recursive resolver A returned a NXDOMAIN, that would be
the end of it,
no new queries, the answer has returned name does not exist.
The impact of the additional queries can be significant as well.
