FAQ

Is this plugin safe to use?

Yes, the plugin includes several safety measures:
* Only processes users with ‘subscriber’ role
* Requires administrator privileges to run
* Includes confirmation dialogs
* Provides detailed logging for transparency
* Always backup your database before running cleanup operations

How do I configure the filters?

1. Go to Users → Spam Filter Settings
2. Add your desired keywords and domains
3. Choose your filter condition (AND/OR)
4. Save settings
5. Run the cleanup from the main plugin page

What’s the difference between AND and OR conditions?

• OR Condition – Delete user if they match ANY keyword OR domain filter
• AND Condition – Delete user only if they match ALL keyword AND domain filters

How do include/exclude domains work?

• Include Domains – Only delete users with these email domains
• Exclude Domains – Never delete users with these email domains (e.g., gmail.com)
• If Include is empty, all domains are targeted except excluded ones
• If Exclude is empty, no domains are protected

What’s the difference between trash and permanent deletion for posts?

• Move to Trash – Posts are moved to WordPress trash bin where they can be recovered or permanently deleted later
• Permanent Delete – Posts are immediately and permanently deleted from the database (cannot be recovered)
• Recommendation – Use “Move to Trash” for safety, then review and permanently delete from trash if needed

How long does the cleanup take?

The duration depends on:
* Number of users/posts to process
* Server performance
* Batch size settings
* WordPress cron frequency

For large sites, the process may take several hours but runs in the background.

Can I stop the cleanup process?

The cleanup process runs via WordPress cron jobs. You can stop it by:
1. Deactivating the plugin
2. Clearing scheduled cron events
3. Restarting your web server

What happens if the process is interrupted?

The plugin uses batch processing with progress tracking. If interrupted, you can restart the process and it will continue from where it left off.

Can I customize the spam keywords?

Yes! You can add, remove, or modify keywords through the Spam Filter Settings page. The interface allows you to dynamically manage your keyword lists.

Does this affect my site’s performance?

The plugin is designed to minimize performance impact:
* Runs in background via cron jobs
* Processes data in small batches
* Uses efficient database queries
* Includes built-in delays between batches

Where can I find the cleanup log?

All cleanup activities are logged to: wp-content/uploads/smart-spam-cleaner/smart-spam-cleaner.log

The log file contains:
* Timestamps for all operations
* Number of users/posts processed in each batch
* Success/failure status for each deletion
* Completion messages

Can I use this plugin programmatically?

Yes! You can customize filters using WordPress filters:

add_filter('wwssc_user_filters', function($filters) {     $filters['keywords'][] = 'custom_keyword1';     $filters['keywords'][] = 'custom_keyword2';     $filters['domains']['include'][] = 'spamdomain.com';     $filters['domains']['exclude'][] = 'trusted.com';     $filters['condition'] = 'AND';     return $filters; }); add_filter('wwssc_post_filters', function($filters) {     $filters['keywords'][] = 'custom_keyword1';     $filters['keywords'][] = 'custom_keyword2';     return $filters; }); 

Can I change the batch size?

Yes! You can configure batch size in the settings page (range: 50-2000).

You can also define a custom batch size in your wp-config.php file:

define('WWSSC_BATCH_SIZE', 1000);
