[...] Die AdBlocker temporär zu umgehen wäre grundsätzlich möglich (zb Ändern von URLs, Server Side Includes der Ads), ist aber bei grösseren Werbenetzwerken schwierig und kommt schlussendlich einem Katz und Mausspiel zwischen Adblocker und Werbenetzwerk gleich. Einige Seiten versuchen AdBlocker zu detektieren und zeigen dem Endbenutzer dann einen Warnhinweis an, appellieren an seine Loyalität den Werbeblocker abzuschalten(zb bei tvshack hab ich das mal beobachtet). Eine Beschreibung der Vorgangsweise der Erkennung von installierten Werbeblockern findet sich bei thepcspy (Javascript Test auf Höhe eines iFrame, in das eine Google Werbung geladen wird. Wenn = 0, dann Werbeblocker), eine Demo der Detection und Warnhinweis findet sich unter adblock.org [...]

I have devised a script snippet that will work perfectly

Just put this inside the DIV / Wrapper of your adds below the add-call script and adjust the css/message to suit yourself

[code]

Please disable your adblocker and support our site

var div = document.getElementById('topbanner');
if(div.getElementsByTagName('IFRAME')[0] == null){
document.getElementById('blockedalt').style.display = "block";
}
[/code]

This isn’t a test page. With the test variable set to always display the message, it’s impossible to tell if it’s really detecting adblocking software. At this point, it’s more a “javascript enabled” detector.

You’re free to set up your websites however you want, but once code gets to my end, I’ll display it however I want. I block intrusive ads like doubleclick, but I choose to allow stuff like googlesyndication. If your ads are like the ones on this website, I’ll see them. If you or they annoy me, then I block them. I also don’t use filter sets, so if I’m browsing random websites for information, I’m more likely to see ads.

This code sample doesn’t work,.. banner.gif (the bait) does not get blocked, however the script detects that it does. This false alarm doesn’t prove functional for a production site trying to reclaim its advertising viewership.

Thank you for your efforts on this issue.

Seems odd that your post has been up since July and yet no-one has mentioned that the spelling “recieve” is incorrect on your pop-up.

It claims I’m running Adblock software in both Firefox and IE. This is only true for Firefox. Perhaps it’s a bug?

I noticed that the window still appears even if I have Adblock disabled when I load the page.
