Bad Behavior prevents spammers from ever delivering their junk, and in many cases, from ever reading your site in the first place.
Bad Behavior 2.2 requires MySQL 5.0 or later and PHP 5.2 or later.
CloudFlare users must enable the Reverse Proxy option in Bad Behavior's settings. See the documentation for further details.
Bad Behavior is unable to protect internally cached pages on MediaWiki. Only form submissions will be protected.
When upgrading from version 2.0.19 or prior on MediaWiki and WordPress, you must remove the old version of Bad Behavior from your system manually before manually installing the new version. Other platforms are not affected by this issue.
Bad Behavior on WordPress requires version 3.1 or later. Users of older versions should upgrade WordPress prior to installing Bad Behavior.
On WordPress when using WP-Super Cache, Bad Behavior must be enabled in WP-Super Cache's configuration in order to protect PHP Cached or Legacy Cached pages. Bad Behavior cannot protect mod_rewrite cached (Super Cached) pages.
When using Bad Behavior in conjunction with Spam Karma 2, you may see PHP warnings when Spam Karma 2 displays its internally generated CAPTCHA. This is a design problem in Spam Karma 2. Contact the author of Spam Karma 2 for a fix.
