You doesn't seem to have much in the way of protection. Consider these extensions?

• SimpleAntiSpam - trivial, often works well
• ForcePreview - good luck saving if they don't know to preview first
• SpamBlacklist - set it up to use Wikimedia's lists and you catch a lot
• AntiBot - an extensible framework, comes with one useful thing. Make sure you copy the plugin into the active directory else it won't do anything. Our modification of the genericFormEncoding.php:

$wgHooks['EditFilterMerged'][] = 'AntiBot_GenericFormEncoding::onEditFilterMerged';
class AntiBot_GenericFormEncoding {
       function onEditFilterMerged( $editPage, $text, &$hookError ) {
               if ( !function_exists( 'apache_request_headers' ) ) {
                       return true;
               }
               $headers = apache_request_headers();
               if ( isset( $headers['Content-Type'] )
                       && $headers['Content-Type'] == 'application/x-www-form-urlencoded' )
               {
                       global $wgUser;
                       if ( !$wgUser->isAllowed( 'noratelimit' ) && !$wgUser->isAllowed( 'bot' )) {
                               if ( AntiBot::trigger(__CLASS__) == 'fail' ) {
                                       return false;
                               }
                       }
               }
               return true;
       }
}

• AbuseFilter - configurable blocks against particular behaviours. A couple of filters we use on WikiFur (use import on Special:AbuseFilter to apply):
