Plugin Conflict – Cleantalk interfering with WP_User_Query in admin area

Description: We’ve identified a compatibility issue between Cleantalk Anti-Spam and custom admin pages that use WP_User_Query.

The Problem:

• Custom admin page uses WP_User_Query to display a paginated list of users (20 users per page)
• With Cleantalk enabled, the page fails to render the user table completely
• With Cleantalk disabled, the page works perfectly
• Error logs show memory exhaustion in CleantalkWpDieOnComment.php

Environment:

• WordPress with ~4,000 users and ~250,000 posts
• PHP 8.x with 256MB memory limit
• Simple WP_User_Query with basic pagination

Expected Behavior: Cleantalk should not interfere with admin-area user queries that are clearly for administrative purposes, not spam checking.

Suggested Fix: Cleantalk should check if the current request is in the admin area (is_admin()) and skip heavy processing for administrative user queries.

This appears to be Cleantalk hooking into pre_user_query, users_pre_query, or similar WordPress user query hooks and adding processing that’s unnecessary for admin pages.
