When I started using b2evolution, I received quite a few warnings from different people that it’s a giant spam magnet. I gave it a few months and my trackback and comment spam volume is simply enormous, despsite b2’s centralized anti-spam list. I have finally broken down and ported everything over to WordPress. Installation was a snap and only took me a few hours to port my skin over. So far, I am very happy with it 🙂 No wonder it’s so popular!
