Dear colleagues,
Following up from his earlier posts on RIPE Labs, John Quarterman is now looking at 'ASN Ranking Correlations Between Spam Blocklists':
http://labs.ripe.net/Members/jsq/asn-ranking-correlations-between-spam-block... st
I skimmed this document, and I'm still not 100% sure that I have grasped the ultimate point. It begins thus: "Comparing ASN rankings by spam volume from two different data sources... indicates there is enough correlation to have confidence in the rankings." Yes. And? This is a little like saying that the track records of multiple meterologists do indeed indicate that yes, by and large they generally seem to get it right. But then what is the functional value of that knowledge? Is the point here that I can leave my umbrella at home when two or more of them say that it's not going to rain today? Is the point of Mr. Quarterman's study that certain entire ASNs may be safely or reasonably blacklisted? Regards, rfg
