Defensio; outsmarting evil spam
September 29, 2007Recently I received some information about a new way to fight spam. Some guys from Canada really hate spam and developed a new anti-spam routine called Defensio.
This new routine is more accurate then anything known at this point (*cough*Akismet*cough*) and actually makes managing spam comments a breeze. This project is still in beta right now, but is scheduled to go live pretty soon. The last few days I’ve been working on a Pixelpost addon that uses Defensio. It wasn’t easy, we had to upgrade the look of the comments section in Pixelpost to make it work but I finally managed. And today is the day I put it to the real test.
I disabled all other anti-spam measurements on my photoblog and rely solely on Defensio (and my coding skills). Hopefully Defensio does a better job then Akismet.
Let me provide you with some stats for the last 275 days on my blog. Around 98% of all the comments where spam and these were all blocked by my defensive lines. My defensive lines consists of several things: accepting no urls in comments, using the token and the Project Honey Pot addon (PP1.7 only)
Additionally, 64% of the 2% that got through my defensive lines were also spam which I had to deleted manually. My best lines of defense are currently the Token support and the Project Honey Pot addon. But still these things will let spam through and hopefully Defensio will do a better job.
In a couple of days I’ll post my results here and in the mean time I’ll just keep my fingers crossed
