It appears that Rubens Kuhl <rubensk () gmail com> said:
It's perfectly reasonable to claim a database right in the WHOIS data,
but the offense is scraping WHOIS, not enumerating the DNS zone. ...

The zone file could be seen as an accessory to the database rip-off.
For instance, it would be hard to see such a dependency on Alexa 1M
top domains, since they are already enumerated. But some spam actors
deliberately compared zone file editions to single out additions, and
then harass the owners of newly registered domains, both by e-mail and
phone.

Yeah, I know, and some of us download and diff zone files every day to
see what's new to track abuse trends.  That doesn't annoy anyone other
than perhaps people whose phish campaigns it might disrupt.

Once again, the issue is WHOIS scraping, not the DNS.
