The log chart shows AS 46475 LIMESTONENETWORKS won by spamming ten times more than any other  U.S. ASN for the last week of the month.
Conversely, AS 21788 NOC spammed more than any other ASN in this top ten early in the month, but then mostly cleaned up its act.
In between, AS 23352 SERVERCENTRAL was number 1 in the middle of the month, after coming up from almost nothing.
Poor Comcast, reduced to a lowly third place. AS 20214 COMCAST-20214 did spam a third less last month (2,193,898), but it was the spontaneous spam spewing of the two top place newcomers that pushed it down.
Yet Comcast really won the month. It took 4 of the top 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.
And AOL placed this month, with AS 1668 AOL-ATDN.
