Take into account the use of hijacked computers and the whole economics model is blown to bits since using those computers does not incur any cost. Combine that with the 70% figure provided by MessageLabs for use of hijacked computers and we are all in deep trouble.

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.
