Virus Bulletin updated its spam filter test, and found that compared to last year, spam filters are doing worse. Sadly, the detailed results are only for paid subscribers. But Virus Bulletin published a brief summary of the latest result as a teaser .
I think this is not all bad news. To understand this, one has to consider that the overall volume of spam has dropped significantly. The take down of some large botnets removed a lot of easy to classify spam off the net, leaving a more diverse "spam zoo" that is not as easy to classify. So I don't think this trend is as "worrying" as Virus Bulletin makes it sound.
