Well, it´s quite interesting to see, that the comment-spam in my weblog concentrates on several keywords in my entries. Some weeks ago I blogged about K*A*Z*A*A (you know why put in the stars now ;-), and just in the comments to this article all spam concentrates. So my idea of a blacklist for weblogs might be useful? It works very fine for my e-mail account, too. What do you think?
