After installation, go to the Dam Spam settings in your WordPress admin to:

Configure CAPTCHA settings if desired

Differences from Stop Spammers

Dam Spam is a fork of Stop Spammers. While the core spam protection functionality remains similar, Dam Spam’s file and code structure has been significantly cleaned up and modernized.

Addon Support

Dam Spam supports custom spam checks via addons. Create a separate plugin with this structure:

<?php /* Plugin Name: Dam Spam Addon Example Description: Custom spam check addon for Dam Spam Version: 1.0 */

add_filter( 'dam_spam_addons_block', function( $addons ) { $addons[] = array( __FILE__, 'My_Spam_Check' ); return $addons; } );

class My_Spam_Check { public function process( $ip, &$stats, &$options, &$post ) { if ( $ip === '123.45.67.89' ) { return 'Blocked by custom check'; } return false; } }

Hook into dam_spam_addons_block or dam_spam_addons_allow

Return an array with your file path and class name

Create a class with a process() method

For dam_spam_addons_block: return false to continue checking, or a string to block

For dam_spam_addons_allow: return false to continue checking, or a string to approve
