Review from Gemini:

The changes in src/wp-admin/network/users.php are well-implemented and adhere to WordPress coding standards.

Here's a summary of the review:

• HTTP Status Codes: Explicitly adding 403 to wp_die() calls for unauthorized actions is a good practice for proper HTTP response handling.
• New Filter: The introduction of the network_user_spam_propagate_to_blogs filter provides valuable flexibility for developers to control spam status propagation. The associated PHPDoc block is correctly formatted and includes the @since 6.9.0 tag, parameter descriptions, and type hints.
• Security Enhancement: The addition of is_super_admin() checks for both "spam" and "notspam" actions prevents unauthorized modification of network administrators, which is a significant security improvement.
• Multi-network Compatibility: The refinement in the "notspam" logic to include && get_current_network_id() === $details->site_id ensures that blog status updates are correctly scoped to the current network, improving behavior in multi-network installations.
• Indentation and Readability: The code maintains consistent indentation and remains highly readable.

Overall, these changes improve security, flexibility, and correctness within the WordPress network user management.
