Hello @Someone07 !

There are several ways to detect the using of AdBlockers (taking from the Web):

• Attempt to load the headers of an actual ad library (Google Adsense, Twitter, Facebook, etc…). Check if the request is blocked.
• Insert a dummy ad or attempt to load a dummy ad library. Check if it is removed when the page loads.
• Finally, use an adblocker detection library.

Guess the first point is the most reliable - just take the response from the adv network.
