Detect if a user is using an Ad Blocker
Based on: https://github.com/sitexw/BlockAdBlock
Load the block-adblock.js file:
<script src="block-adblock.js"></script>
Add the Custom Element anywhere on your HTML page:
<block-adblock></block-adblock>
By default, the element will render a red alert at the top of the web page stating that it's detected an adblocker. You can of course customize the script in any way you like.
