Congratulations to Turkcell SuperOnline‘s AS 34104 GLOBAL 64,658 for dropping off of the top 10 spamming ASN’s for Turkey in the May 2012 SpamRankings.net!

It was replaced in the Turkish top 10 by academic network ULAKNET‘s AS 8517, which had previously dropped off the April rankings.

Perpetual winner and still champion for spewing spam from Turkey is TTNET‘s AS 9121, accounting for almost 3/4 of all spam seen from Turkey seen by CBL. SpamRankings.net saw about the same proportion of Turkish spam coming from TTNET in data from PSBL.
