As of last week, Akismet had blocked 100,000 spam comments from this blog. Yes, you read right, a cool hundred thousand. In respect for that milestone, would like to go on record as a paid subscriber of Akismet as of next month. Weblogtoolscollection.com has seen its share of spam and was mentioned in one of the blog updates of Akismet with numbers hovering in the 99.51% comment spam range. Akismet has served me well barring a few offbeat social spam comments and I feel that the developers deserve to be rewarded for their efforts and their service (though I wish I would make anywhere near the money that paid subscribers are supposed to be making from their blogs).
I was in the spam mitigation business with CSPAM and Three Strikes and though the service could only handle a few thousand blogs on my old server, it was quite a trip. It mostly managed itself and I was almost completely spam free during the time I used it. Even though I would like to think that CSPAM was the spark that led to Akismet (Matt and I talked briefly about CSPAM), I am sure the Akismet engine is much more sophisticated and optimized (and not written in PHP like CSPAM). The numbers and processing power needs can be astronomical from my experience. In about nine months CSPAM caught and removed about 700,000 spam comments, had a 10,000 word vocabulary and learned about ten comments a minute. In comparison, Akismet has caught 3,812,040 spam comments and growing and shows absolutely no signs of slowing down. Kudos to the developers.
In short, spam is down, real comments are up and I am a happy camper. I would encourage everyone to try Akismet for their Spam needs. I also urge heavy users to put their money where their Spam was and sign up as a subscribed user.
