Dougal Campbell's geek ramblings

Has anybody else noticed a sharp increase in blog spam activity lately over the past couple of weeks? The number of firewall rules on my system generated by SpamValve was down below 40 not too long ago, but now it’s back up to over 100 again. The worst of the attacks still cause some brief hiccups on my server from time to time, but now that I’ve got a good set of automated countermeasures in place, I typically don’t notice it until after the fact.
