Step 2. Edit wp-content/plugins/wp-ban/wp-ban.php

1. Open wp-content/plugins/wp-ban/wp-ban.php for editing using your favorite text editor.
2. Somewhere after the following line

   add_action('init', 'ban_textdomain');

   add the following function definition.

   ### Function: Process Banned Bad URL
   ### http://www.microshell.com/website_internet/security/updating-wp-ban-to-include-bad-urls
   function process_ban_bad_url($banned_bad_urls, $against) {
   	// We should never ban wp-admin.
   	if(!empty($banned_bad_urls) && !preg_match('/^\/wp-admin/', $against)) {
   		foreach($banned_bad_urls as $banned_bad_url) {
   			// Let's never ban wp-admin URLs.
   			if (strstr($against, $banned_bad_url) !== false) {
   				print_banned_message();
   				break;
   			}
   		}
   	}
   }
   

3. Find the function definition for banned() and add the following PHP line near the variable definitions.

   $banned_bad_urls = get_option('banned_bad_urls');

4. Under the same banned() function definition, under the following block:

   if (!$is_excluded)

   add the following line:

   process_ban_bad_url($banned_bad_urls, $_SERVER['REQUEST_URI']);

5. Find the function definition for ban_init() and add the following lines. I recommend adding them on the appropriate section within the function. However, if you add them anywhere in the function, it should be fine.

   // http://www.microshell.com/website_internet/security/updating-wp-ban-to-include-bad-urls
   $banned_bad_urls = array();
   
   add_option('banned_bad_urls', $banned_bad_urls, 'Banned Bad URLs');
