Welcome to a whole new way of keeping your blog, forum, guestbook, wiki or content management system free of link spam. Bad Behavior is a PHP-based solution for blocking link spam and the robots which deliver it.
Bad Behavior is one of the Internet’s most trusted solutions for helping to prevent link spam and other malicious activity, from well-known sites to the smallest blogs.Read More on Who Uses Bad Behavior »
Bad Behavior complements other link spam solutions by acting as a gatekeeper, preventing spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place. This keeps your site’s load down, makes your site logs cleaner, and can help prevent denial of service conditions caused by spammers.Read More on Features and Benefits of Bad Behavior »
Bad Behavior also transcends other link spam solutions by working in a completely different, unique way. Instead of merely looking at the content of potential spam, Bad Behavior analyzes the delivery method as well as the software the spammer is using. In this way, Bad Behavior can stop spam attacks even when nobody has ever seen the particular spam before.Read More on How Bad Behavior Works »
Bad Behavior is designed to work alongside existing spam prevention services to increase their effectiveness and efficiency. Whenever possible, you should run it in combination with a more traditional spam prevention service.Read More on Preventing Spam With Bad Behavior »
Bad Behavior works on, or can be adapted to, virtually any PHP-based Web software package. Bad Behavior is available natively for WordPress, MediaWiki, Drupal, ExpressionEngine, and LifeType, and people have successfully made it work with Movable Type, phpBB, and many other packages.Read More on The Bad Behavior Connector »
