I also noticed this snippet of code:

  if(url.indexOf(”google.”)!=-1||url.indexOf(”search.yahoo”)!=-1||url.indexOf(”search.live”)!=-1||url.indexOf(”bing.”)!=-1){
    if($(”#adsense_2719325″).parents(”#right-column”).length > 0 && !isImage){
      $(”#adsense_2719325″).addClass(”afc_wide”);
    }
    $(”#adsense_2719325″).html(ads);
    $(”#ads-section-2719325″).show();
  } else {
    $(”#ads-section-2719325″).hide();
  }
