title: Customize User Agent Filtering

The `user_agent_items` filter changes which User-Agent substrings Filter Suspicious Queries blocks.

Matching is a substring search, so you can be broad or specific.

```php
add_filter( 'user_agent_items', 'filter_user_agent_items' );

function filter_user_agent_items( $useragents ) {
  // Copy the line below to add more agents.
  $useragents[] = 'seekportbot';
  return $useragents;
}
```
