My friend Sergej Müller, Author of wpSEO, published a new WordPress Antispam Plugin . I had the pleasure to try out this little bee in a beta version on WPengineer.com. Since the installation on December 31st 2008 we didn't have one spambot!
His solution is very simple but genius, this little Plugin goes a complete different way than other Antispam Plugins, it just replaces the comment field, but he won't give away any more details... 😉
The installation is very easy: Upload Plugin, activate and done! To be sure, write a test comment, since this Plugin exchange your comment field. I didn't have any problems with it.
So far the documentation is only in German, but I'm sure that will be changed soon. 🙂
Try it out and say goodbye to Spam!
