Would there be many FNs (missed spams) if we whitelisted all of these? In other words are these all truly False Positives? If not, which ones do you feel are true spammers and why.

If WS and SC agree on something (or even more of the SURBLs) they might have a point. I tried to check kit.net (found in your list), and got an "unknown host" error. So maybe that was a FN (= spammer).

I also tried to check made.com (on your original DMOZ list, it was listed in SC and AB IIRC), and came to the conclusion that this might be a Korean hoster. The subdomain listed in DMOZ looked pretty ordinary (at least the non-Flash part), no offers to buy something. But that could be misleading, I didn't visit the site with enabled JS. And of course the reason for the SC listing could be another subdomain, not the one listed by DMOZ. But made.com could be a FP (?)

Hard to judge. More than one bit in multi is a hint. Bye.
