AdBlock Detect - js script for your site
AdBlock Detect - install on your site a warning to visitors to turn off the ad blocker.

Now many people use various browser plugins to disable ads on the sites they visit, however, these sites cannot work for a long time without advertising monetization.
With this script, we can warn the visitor who uses an ad blocker to add our site to the whitelist.
If you severely restrict access to the site to a visitor with a blocking plugin, then most likely he will simply leave your site.
As we know, Google does not like sites that have a high bounce rate. With this script, we can only harm our site by accident.
Deciding whether to enable the blocker or not is up to each webmaster.
