Fuckadblock only recognizes that Adblock is turned off after many refresh on the page

Question

Hello, I’m trying to implement the ebit banner but I’m having problems with adblocks. In my previous question (ebit banner with 404 error and infinite loop with Adblock on) I was able to implement fuckAdBlock to block ads, but it is not recognizing when Adblock is not activated. Only after several refreshes on the page does it work.

This is my code:

document.addEventListener("DOMContentLoaded", function(){
   function adBlockNotDetected() {
     console.log('anuncio NAO bloqueado');
 }

 // Function called if AdBlock is detected
  function adBlockDetected() {
      //>>esta bloqueando mesmo sem o adBlock estar ativo<<
      console.log("Anuncios bloqueados");
  }
  
  if(typeof fuckAdBlock !== 'undefined' || typeof FuckAdBlock !== 'undefined') {     
      adBlockDetected(); 
  } else {     
      var importFAB = document.createElement('script'); 

      importFAB.onload = function() {          
          fuckAdBlock.onDetected(adBlockDetected);
          fuckAdBlock.onNotDetected(adBlockNotDetected);
      }


      importFAB.onerror = function() {        
          adBlockDetected(); 
      }

      importFAB.src = 'https://cdnjs.cloudflare.com/ajax/libs/fuckadblock/3.2.1/fuckadblock.min.js'; 
      document.head.appendChild(importFAB);
  }
 });
 </script>

I found a post similar to mine https://stackoverflow.com/questions/45980660/detect-ad-block-script-runs-properly-only-on-hard-reload but when I add the fuckAdBlock.check(loop); he makes a mistake.

document.addEventListener("DOMContentLoaded", function(){ fuckAdBlock.check(loop); }); 

I don’t know if I wrote it right, because I didn’t want to use jQuery....
