We’ve already looked at
TTNET,
which
pushed 
Turkey to the top of the spamming world in July 2012,
and
KOCNET, ditto in August.
What about other Turkish ASNs?
The next five are
AS 12735 ASTURKNET,
AS 12978 DOGAN-ONLINE,
AS 16135 TURKCELL,
AS 29179 KIBRISONLINE-AS,
and
AS 8517 ULAKNET,
in the August 
from both
CBL
and
PSBL data.
You guessed it: they’re all infested with Festi botnet, too.
