I've noted a spam slowdown. At first, I noticed a decline in links to EXE files. Now I am noting a reduction in SPAM experiments. This includes hiding a url, letter by letter in an HTML table. This seems to corolate witht the slowdown in other sectors of the American economy. Namely, the reduction in raw materials to Brazil, Russia, India and China. (Labeled, "the drop of the bric" by Jim Crammer of Mad Money on CNBC).
To this I am adding that my spam filters have jumped from 2-4% pass through to 1/2 of 1%. That is to say, usually I have 2-4% of all spam that makes it through the spam filter (given I get every payload marker). It appears that I am catching 99.4% now. I don't think my filters are better, or that I have all their domains, or payoff domains. I should also mention that the penny stock scams have stopped too.
I think in a few weeks we will know the answer.
