Aggressive Anti-AdBlock is an advanced JavaScript tool that robustly detects and counteracts ad blockers. It now features aggressive persistence mechanisms, smart resource optimization, and multi-vector detection. If a blocker hides or removes the warning, it re-appears instantly, immune to simple CSS hiding tricks or DOM deletion. The script uses multiple bait techniques, AdSense-specific scanning, and iframe detection to ensure ad blockers are reliably detected. Lightweight, flexible, and CPU-friendly thanks to its new cooling system.
- Aggressive Persistence: The modal now actively protects itself by rotating its HTML ID every second and enforcing
!importantstyles. This prevents users from hiding it using static CSS rules or Developer Tools. - Smart Cooling System: To save your users' CPU, the detection loop switches from "Aggressive" to "Passive" mode after 30 seconds. It re-engages instantly if the user switches tabs or reloads.
- Cache-Busting Bait Refresh: The script actively moves bait elements in the DOM to force the browser to re-evaluate styles, defeating blockers that rely on cached rules.
- Enhanced AdSense Shield: Now scans all AdSense units on the page for class manipulation or hidden attributes, ensuring legitimate ads aren't silently blocked.
- Anti-Tamper Logic: Detects and fixes advanced evasion techniques like negative
z-index,clip-pathmasking, andopacityhacks. - Custom Container Monitoring: New ability to monitor specific IDs of your own ad containers. This acts as a countermeasure against native browser blockers (like Brave, Edge, Chrome, Opera, Vivaldi, Samsung Internet, Adblock Browser) that remove elements without using traditional extensions.
The following popular ad blocker extensions will no longer work on your site after these updates:
The script works with most extensions; however, some employed advanced techniques to evade detection. With the latest changes, these and many others are no longer effective.
- Advanced detection of AdBlockers using multiple bait techniques (Generic & AdSense).
- Self-Healing Modal that regenerates if deleted from the DOM.
- CSS-Proof Design: Rotates IDs and checks for
visibility,display,opacity,z-index, andclip-path. - Native Blocker Countermeasure: Capable of detecting blocks from Brave, Edge, Chrome, Opera, Vivaldi, Samsung Internet, Adblock Browser, and other distinct browsers by monitoring your actual ad containers.
- Iframe forced-style detection to catch advanced hiding techniques.
- Performance Optimized: Uses
requestAnimationFrameprinciples and idle checks (Cool-down mode). - Easy to integrate into any website.

<script src="https://cdn.jsdelivr.net/gh/JStivenCM/Aggressive-Anti-AdBlock/Aggressive-Anti-AdBlock.min.js"></script>Aggressive-Anti-AdBlock.js or a CDN may lead to ad blockers detecting and blocking it via URL filtering. It is strongly recommended to copy the code from Aggressive-Anti-AdBlock.js and integrate it directly into your main JS bundle or rename the file.
The script runs automatically when the page loads. To customize the modal, edit the config object in the script:
checkInterval: Time in ms between checks (default:2000).ids.watchedAdContainers: Array of IDs of your legitimate ad containers to monitor (e.g.,['ad-sidebar', 'banner-top']). Essential for catching native blockers.⚠️ Important: Ensure these elements are present and visible on ALL devices (Desktop & Mobile). If an element is hidden by your own responsive CSS (e.g.,display: noneon mobile), it will trigger a false positive.image.src: Change the warning image URL.message.innerText: Modify the warning text.reloadButton.innerHTML: Customize the button text/icon.
