WordPress Zero Spam is the latest to join the ranks of anti-spam plugins fighting on the front lines of WordPress sites. The new plugin is based on a simple method created by Mozilla developer David Walsh, whose popular tech blog gets regularly hammered by 8,000+ spam comments per day.
After two weeks of employing this method, Walsh claims to have brought his spam comments down to zero. “I went from over 8,000 per day to none. Better than Akismet, better than any plugin.” Inspired by Walsh’s success, web developer Ben Marshall packaged the method into a WordPress plugin with an enticing tagline: “Just install, activate and say goodbye to spam.”
WordPress Zero Spam is different from Akismet, the most often recommended spam blocking solution, in that it’s not a service dedicated to filtering spam. It simply checks for bots and discards spam comments at the door before they reach your site. The benefit here is that you are likely to have fewer spam comments and false positives to hunt through. Since it’s an open source plugin and not a service, WordPress Zero Spam is free for both personal and commercial use.
