Whither spam?

Totally unrelated to drug policy… While you occasionally see a spam comment that gets through the filter, the vast majority of them are filtered by Akismet, which keeps statistics of the filtering it does on this site.

Sometime in late March, there was a remarkable drop-off in spam comments, and I’m curious as to whether anyone knows why this is (prior to that point, the numbers had been growing each month as more spammers became aware of the site).
