There's nothing secret about the existence or purpose of the list.

I don't know enough about Barrett to guess as to whether or not he'd 
qualify.

Also, I was considering emailing Barrett privately, but since there seems 
to be so much misinformation going around, others will probably benefit 
from this.  If you want to send out list of IPs suspected of being bots or 
really any other class of insecure/0wn3d systems, to make it easier for 
those who care to find their IPs in your list, run it through the Team 
Cymru whois server first.

http://www.cymru.com/BGP/whois.html

Then sort the list numerically by ASN.  That way, people can scroll 
through it, or search by ASN, and quickly determine if there's any further 
action worth taking.

It's also a really good idea to include timestamps, ideally exact ones in 
GMT per IP.  In this case (unix bots) it's not as likely, but typical 
windows bots frequently show up on end-user systems with dynamic IPs. 
Telling me one of my dial pool IPs was a bot "recently" is not as useful 
as telling me it was a bot 2005-12-25 02:30:45 GMT.
