The legal issues that are affecting the Spamhaus are heating up. If Spamhaus were shut down, even temporarily, then the increase in spam that makes it around the Internet would be significant.

Regardless of the figures and the discussions (including those on the Slashdot page for the story), any increase in spam would be a bad thing.

I don't know what your email statistics are like, but for me about 98% of all the email I received in the last year is spam. An increase of any kind would be bad and there's been a recent splurge of spam in my inbox that has required some changes and improvements to my filters and techniques.
