Detecting AdBlocking software?

Question

I was recently visiting a site and noticed that the page had a section that said it noticed that I was using AdBlocking software and could I kindly turn it off to help suppo

Answer 1

I found this part in the code which seems to look like how they did it:

/*MOOTOOLS*/
window.addEvent('domready', function(){

$$('.cat-item').each(function(el) { 
    var fx = new Fx.Morph(el,{ duration:300, link:'cancel' }); 
        el.addEvents({ 
        'mouseenter': function() { fx.start({ 'padding-left': 25 }); }, 
        'mouseleave': function() { fx.start({ 'padding-left': 15 }); } 
        }); 
    });

    if ($$(".google-sense468")[0] && $$(".google-sense468")[0].clientHeight == 0 && $('block-warning')) $('block-warning').setStyle('display','block');

});
/*MOOTOOLS END*/
