Определение блокировщика рекламы безопасность

Для определения блокировщика рекламы использую расширение fuckadblock, оно безопасно? вставляет ли данное расширение свою рекламу ко мне на сайт?

 // Function called if AdBlock is not detected
// Function called if AdBlock is not detected
function adBlockNotDetected() {
//  alert('AdBlock is not enabled');
blokreklama=10;
}
// Function called if AdBlock is detected
function adBlockDetected() {
//  alert('AdBlock is enabled');
blokreklama=11;
}

// We look at whether FuckAdBlock already exists.
if(typeof fuckAdBlock !== 'undefined' || typeof FuckAdBlock !== 'undefined') {
    // If this is the case, it means that something tries to usurp are identity
    // So, considering that it is a detection
    adBlockDetected();
} else {
    // Otherwise, you import the script FuckAdBlock
    var importFAB = document.createElement('script');
    importFAB.onload = function() {
        // If all goes well, we configure FuckAdBlock
        fuckAdBlock.onDetected(adBlockDetected)
        fuckAdBlock.onNotDetected(adBlockNotDetected);
    };
    importFAB.onerror = function() {
        // If the script does not load (blocked, integrity error, ...)
        // Then a detection is triggered
        adBlockDetected(); 
    };
    importFAB.integrity = 'sha256-xjwKUY/NgkPjZZBOtOxRYtK20GaqTwUCf7WYCJ1z69w=';
    importFAB.crossOrigin = 'anonymous';
