You can do that but what purpose will you achive.
You can not have that image clickable so its not going to make any $$$ for you.

Right. You could however put in a non clickable add with a url on the image, which could be usefull for some webmasters.

This image is what your visitors will see before the ad is loaded.

That would get you banned on Google, "undue attention"

Likely someone with an Adblocker isn't going to click on it anyway. Yea, there are some that get installed without the user's knowledge, but I believe that most people who run them run them for a reason.

Whenever I visit this forum, I wear special glasses that prevent me from seeing any posts made by people whose viewpoints don't agree with mine.

Wow. This is great!

I had developed and used some very robust ad-blocking countermeasures in the past. I was able to detect almost all instances of ad-blocking and one could not gain access to my content while blocking my ads without disabling both JavaScript and CSS. My countermeasures were highly effective even against greasemonkey, proxo and adblock.

I ran my countermeasures for over two years and what I determined is that around 4-10% of real human users block ads. What I didn't like about the countermeasures is that they added bloat to my code and delayed the display of my pages for users who were not blocking ads.

I disabled my countermeasures earlier this year because my original reasons for blocking users who blocked my ads were no longer issues. I'd only recomend blocking users who block ads if this is a major problem on your sites. It also might be more effective to simply modify the types of ads you use on your site and to harden your ads against being detected (e.g. removing height and width clues).

If you would like the URL to the article I wrote on this issue and the URL where you can see my countermeasures in action, send me a private message.

Ken, I thought about doing this for a long time too, but decided against it essentially for the same reasons. One question: did you ever get any complaints/flack from visitors for doing this?

Occasionally. Normally they revolved around when my tactics were being discussed in some ad blocking forum. I think the loudest complainers were the ones who would not have known about my site if it weren't for the fact that my tactics were being discussed.

I did participate in some of the ad blocking discussions about my tactics, which helped me strengthen my countermeasures and went a long way towards getting people to look at both sides of this issue.

The big thing was that when I started using my countermeasures, main line security programs like ZoneAlarm and Norton Internet Security (NIS) were really pushing their ad-blocking ability as a security feature. In fact NIS had its ad-blocking enabled by default. Opera was also displaying ads on their tool bar while giving users rudimentary ad-blocking ability for on webpage ads. Since then, ZoneAlarm has deemphasized their ad-blocking ability (which is not that good anyways), NIS now ships with its ad-blocking turned off, Opera has gotten rid of their toolbar ads. Firefox's AdBlock extension has also been extended with Adblock Plus, which has a site white listing option, which is highly effective at exempting white listed sites from their ad-blocking.

Other factors that have changed since I initially implemented my ad-blocking countermeasures is that ad revenues have greatly improved since the introduction of Google AdSense and bandwidth costs have dropped tremendously. As a result, ad-blocking causes less financial problems than it did three years ago. With this said, academic institutions and corporations are starting to use more and more network wide ad-blocking solutions that users have no control over.

Basically, I think the rate of ad-blocking has basically leveled out and one can get their traffic to out grow the harm caused by current ad-blocking rates. One thing that would really help to reduce the demand for ad-blocking is if web publishers would exercise a little more restraint with the nature of ads they display on their websites. For instance, I've found it necessary to install the Flashblock extension for Firefox, because Flash ads kept freezing up and/or crashing Firefox and getting bombarded by sound at inappropriate times was really annoying. I personally have tried to limit the nature of ads I display on my websites and have tried to shift my advertising over to text based ads as much as possible. At the same time, I try to design the ads that I sell directly to advertisers to be virtually impossible to block.
