I must agree. The only content criteria we have for SURBLs is inclusion in spam and exclusion in ham. Aside from the phishing list (which also happens to be very spammy), all the SURBL lists contain spam domains. Spam versus ham should remain our only criteria for inclusion or now.
Well, I think this info should be told to everyone who is an admin. You all know I'm interested in this because I send the info direct to the FBI SA contact I have.
The official place to report such sites is www.missingkids.com
Also the site mentioned simply redirects to http://218.189.199.18:2180/portal/portal/pbf/
If you have any more info on this site, let me know OFFLIST, and I will submit to the Special Agent.
Thanks
