John Quarterman on Mapping Spam and Politics (audio)

At a meeting on a completely different subject, I was interviewed about SpamRankings.net. Here's the audio, and here's the blurb they supplied:

John S. Quarterman, long time Internet denizen, wrote one of the seminal books about networking prior to the commercialization of the Internet. He co-founded the first Internet consulting firm in Texas (TIC) in 1986, and co-founded one of the first ISPs in Austin (Zilker Internet Park, since sold to Jump Point). He was a founder of TISPA, the Texas ISP Association. Quarterman was born and raised in Lowndes County, where he married his wife Gretchen. They live on the same land where he grew up, and participate in local community and government.

Quarterman took some time during Georgia River Network's Weekend for Rivers to speak with the Nonprofit Snapshot about spam-mapping and small town politics.

More about Elinor Ostrom's Nobel-prize-winning work on organizing the commons, and how that applies to SpamRankings.net.

The water organization has since been incorporated as the Georgia non-profit WWALS Watershed Coalition:

WWALS is an advocacy organization working for watershed conservation of the Willacoochee, Withlacoochee, Alapaha, and Little River Systems watershed in south Georgia and north Florida through awareness, environmental monitoring, and citizen advocacy.


Comcast pushed out of first, yet wins November U.S. SpamRankings.net

How can an ISP both lose and win in top 10 rankings? By placing more than once!

Comcast got pushed out of first place by AS 46475 LIMESTONENETWORKS and AS 21788 NOC in the November 2011 Monthly U.S. SpamRankings.net from CBL volume. AS 20214 COMCAST-20214 did spam a third less (1,503,173 spam messages) than last month (2,193,898), but it was the spontaneous spam spewing of the two top place newcomers that pushed it down to third place.

Yet Comcast really won the month. It took 4 of the top 10 (places 3, 6, 7, and 10), which is twice as many as last time, and accounted for 30.29% of top 10 spam spewed, up from 23.9% last time. That percentage beats either of the top two this time.


China does not lead Country Rankings from SpamRankings.net

An area where China does not lead the world: Country rankings by SpamRankings.net. China is only #13, but Brazil, Russia, and India (the other three BRICs) are in the top five countries by total spam messages for October 2011. U.S. is #10.

Vietnam came from behind a few months ago to place second for October.

Brazil had slumped as low as #6 in July, but has pulled back up into the leading pack.

After the top five, it’s a long-tail distribution indeed. Continue reading

The Big Drop: medical to zero in SpamRankings.net

A surprise in the July SpamRankings.net rankings: US medical rankings all went to zero by 14 July. World medical rankings went from hundreds and thousands to near zero between 17 and 24 July.

That’s in rankings from CBL data. PSBL shows much less data for medical organizations, yet nonetheless the same effect in both world and U.S. medical rankings.

No other rankings showed such a drop.

Did medical organizations actually clean up their act? Or did they just manage to whitelist their netblocks at CBL and PSBL?

Either way, it looks like they noticed SpamRankings.net.
