Take into account the use of hijacked computers and the whole economics

The majority of the hijacked computer sent spam we see is just plain old
open proxies. Using an open proxy doesn't give you any extra bandwidth,
it's just an anonymising tool.
Matt, I was not aware of that fact - the article quiting the Message Labs
report made it clear that the 70% figure refered to regular hijacked
computers. Perhaps you can provide us with an extract from that report or a
link to it? Also, for the people doing spam analysis, adding the delivery
method or vector to the analysis might be useful.
