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.
Of course, even 19 million spam messages a month, as for #20, Philippines,
is quite a bit.
