We have not conducted any to my knowledge. In fact, I spent quite a bit of time trying to determine when and why a "without cause" review would make sense, and I was only able to come up with one reason;</pre>

I find it interesting that your "quite a bit of time" did not
include asking the person who wrote that text, i.e. me, or reviewing
the threads here on the subject where the reasoning was discussed
several times--including ones I'm pretty sure you participated
in--or reviewing the transcripts of the meetings where it was
discussed.<br>
<br>
Therefore, I will recap the top reason: to find space that has been
abandoned and is therefore an attractive target for spammers and
other criminals. We're told ARIN spends a lot of time reacting to
hijackings, but IMHO the community would be better served by being
proactive. Returning such space to the free pool would be a minor
side benefit.<br>
<br>
Note that I would <i>not</i> recommend doing this at random; it
should be based on indicators of use such as the time since last
update, visibility in the DFZ, or whatever other similarities y'all
notice between the resources involved in past fraud cases. Go for
the "low-hanging fruit" first and work your way up.<br>

Fears of capricious use of that pre-existing capability in the RSA
were the motivator of NRPM 12: to <i>limit </i>the harm that could
be done if/when ARIN decided to use that power in the future--which
the community seemed to desire in general.<br>
