As a netowork manager, I have noticed a steady increase in spam on our server. It started back in October of last year and has been steadily rising since. We log about 20k spam emails a day now, up from 4k the same time last year. And it is only growing and that is only the ones that I catch in filters. With a .1% miss rate (since most companies that deal with spam often advertise 99.9% which is bogus btw), that means at least 20 are still getting through.
I have also seen a large increase in spam with stock prices in a pump and dump schemes.
