title: How to prevent ad blocker from blocking ads on an app
body: <p>One of my users let the cat out of the bag and told me they were using one of my free apps, which is monetized by ads, but they were blocking the ads with an ad blocker. They told me this mockingly, as if I can't do anything about it.</p>
  
  <p>Can I do something about it? Is there a way to detect that ads are being blocked?</p>
