Anti Adblock how to do?

Question

Ad blocking

I did something like this:

function Check(){
        var element = document.getElementById(ad);
        if(!element) {
            alert('AdBlock обнаружен');
        } else {
            alert("Adblock'a нет");
        }
    }
    setTimeout(Check, 1000);

And it does not work from the word at all, it concludes immediately after the page is launched, what are the ways to detect AdBlock?

Answer 1

Usually in games they don't ban cheaters who don't bother anyone (that is, no one complains about them). Do you know why? Yes, you guessed it, I guess.
On the subject, adblockers usually don't remove an element, but make it invisible (display:none).
