For example, I get a great deal from Asia and South America. I haven't
bothered to calculate a percentage, but it is very substantial, out of
the many thousands of spams I receive each week.
Out of a sample 50,000 spam messages I just checked, it looks like
40% from outside of the US. Of that the breakdown is:
10% CN
6% KR
Everything else is less than 1%. With the countries above .5% being
BR, IT, TW, HK, CA, RU, JP, ES, UK, NL, FR, MX, DE, and AU, in
descending order.
In that sample, coming from outside the US is defined as originating
or passing through a server in one of those countries. With the
exception of the stuff that we get that's actually in Chinese or
Korean (or the very badly written ads for Chinese industrial
companies), I have no illusions about where most of it is really
based.
A quick check for a couple character sets in the subject (which isn't
really accurate, some arrives in UTF8, some arrives assuming the
subject will be in the same character set as the body... not).
GB2312 1.20%
ISO-2022-jp .06%
ks_c_5601 .25%
big5 .11%
8859-3 .06%
windows-1251 .01%
I have no doubt that the percentage can vary quite a bit depending on
your user base. In particular, I know that my personal percentage of
GB2312 is way higher than 1%.

I'm not sure which upsets me more: that people are so unwilling to accept
responsibility for their own actions, or that they are so eager to regulate
everyone else's.
