People say that I am the most patient person on earth. But there are limits to even an extreme patience. I am talking about spam comments on this website. Long time ago I've made my decision to keep this website open. No registration required. No obstacles for people willing to see it, to comment on it. Recently, the number of spam comments increased to the point that I have to react. Akismet does a wonderful job of classifying spam comments. Unfortunately they are in my database until I delete them. My plan is to stop them before they are posted. How?
