Powerful Anti AdBlock Script for Blogger || Adblock Detection Script

🚀 Powerful Anti AdBlock Script for Blogger

Javascript to identify whether ad-blocking behavior is present when a page is being delivered.

Operation

The following web browsers have been tested to identify the behaviors linked to ad blocking using the JavaScript (adblockDetector.js):

Google Chrome

• Mozilla Firefox

• Internet Explorer (8+)

• Safari

The script does this by creating a set of DIVs that are likely to be hidden by browser-based ad blocking tools.

Additional tactics that are not yet included in this script:

URL bait. Allow the detection of network-based ad blocking.
Dynamic bait modification. Update DIV and URL attributes based on the existing blocking lists (Easylist and so on) to make detection more robust.
