I don't think that I agree with "this raises no privacy issues" --
some folk seem to think that they can store "private" information in
the DNS, and if queried for, this may / will expose it. Someone (I
think it was Facebook or LinkedIn) creates (or used to create) a
per-user DNS name for load-balancing purposes -- scraping passive DNS
would allow someone to find many profiles, which could be viewed as a
privacy issue.

I'd much prefer "done correctly, this raises minimal privacy issues"
or "done incorrectly this can raise privacy issues" (or just skip
everything after the semi-colon and say nothing).

I believe that passive DNS is incredibly useful for security stuff, I
just think that saying that it raises no privacy issues could get

Oh, I added the above to the issue.

I don't think the execution is relevant when it was obviously a bad
idea in the first place.
This is like putting rabid weasels in your pants, and later expressing
regret at having chosen those particular rabid weasels and that pair
of pants.
