Trencaspammers - Spam Protection for WordPress

Once again my blog is flooded with comment spam. I installed “Kitten’s Spam Words” and “ThreeStrikesSPAM” to counter the first attack. Those plugins are good enough for a month. Two days back, new wave of spam started. After examining several authimage plugins I chose Trencaspammers, because it is simple to install and get running.

Trencaspammers Setup ( From the readme of the plugin ):

1. Download Trencaspammers from here
2. Unzip trencaspammers1rc.zip
3. copy trencaspammers.php to plugins directory (wp-content/plugins).
4. Activate the plugin from admin login.
5. Edit wp-comments.php ( in wp root directory )
   
   Right after the lines below

   
   	  <textarea name="comment" id="comment" cols="50" rows="8" tabindex="4"></textarea>
   	</p>
   
   

   
   <!-- trencaSpammers- Authimage start -->
   <?php
       $ts_random=rand()
   ?>
   <input type="hidden" name="ts_random"
                   value="<?php print $ts_random; ?>" />
   	<p>
     	<label for="ts_code"><?php _e("Anti-spam code: "); ?>
   
   <img src="/wp-content/plugins/trencaspammers.php?ts_random=<?php print $ts_random;?> " align="middle" />
   	</p>
   	<p>
   	<label><?php _e("Please enter the anti-spam code: "); ?></label>
   	<input type="text" name="ts_code" id="ts_code" size="15" tabindex="5" />
   <-- trencaSpammers- Authimage end -->
   
   

6. Edit wp-comments-post.php ( in wp root directory )
   
   Right after the following line

   
   if ( '' == $comment )
   	die( __('Error: please type a comment.') );
   
   

   Add the following lines:

   
   // trencaSpammers- Authimage start
   $ts_code=trim($_POST['ts_code']);
   $ts_random=$_POST['ts_random'];
   if ( !ts_is_human($ts_random, $ts_code))
   	die( __('Error: please type the security code.'));
   // trencaSpammers- Authimage end
