Spam Karma 2 just keeps on chugging away, protecting my blog from the scum sucking spam roaches of the world. The roaches are getting marginally more intelligent - starting to try to game the spam blockers.
In the wee hours of the morning, some spammer from somewhere in Asia tried to get onto some kind of whitelist by posting a couple of innocuous comments - with no bad links or scary words. Those 2 comments got through, and then they immediately tried to dump spam into the blog. Those comments were automatically killed by Spam Karma 2. It was able to make a distinction from harmless (although pointless) comments from link spam-infested roach fodder.
All I had to do this morning was manually moderate the first two whitelist attempt comments as spam, which took a grand total of 5 seconds. I love Spam Karma 2! :-)
