Since I’ve installed Akismet last year it saved my blog from 100,425 spam comments. It seems to me like an insane amount of spam for an easy going blog like mine, and though I haven’t counted it, I guess only a few hundreds have managed to passed through its defenses. Over that year I kept on reading about other spam plugins and it doesn’t seems to me that there is a better solution yet for bloggers. If you run a wordpress blog or any other comments driven website then you should install it, it’s fast and easy.
