Hello @christophergraves!
Thank you for posting your request!
Please note, that Ad Manager WD does have similar functionality.
If you go to Ad Manager WD > Settings page, you will see an option titled Ad Block Detection. It can be enabled to show a message in case ad blocker extensions are enabled on user’s browser.
The message will appear as an overlay on your website frontend.
With Show message for setting you can select the interval (seconds) during which this message will be displayed.
Furthermore, you can set the message content for Adblock detection using Message to show option.
Please give this a try and let me know in case you have questions.
Thanks! Have a great day!
