State of the Spam-ion 2010 Address

The spam "problem" is getting worse. Since my last report in April 2009 there has been a considerable growth in the volume of spam.

The good news is that the tools used to handle the problem (in particular, SpamSieve) are more than up to the task, so "quality of life" hasn’t really been affected at all.
