A little more technical method is to go into your wrappers/templates or whatever and add div tags there. Something like this:
<div class="myTestAd" style=" text-align:center;margin:10px">
<!-- advert code goes here -->
</div>
<div id=please> Hello friend, would you please not block our ads? Those go to paying for the prizes that we give out and we'd really appreciate your continued support in being able to hand out more prizes. Thank you. </div>
Then add:
<div id=surprise> (right above your forum layout)
</div> (below the forum layout)
Then go to your CSS and add
#please {background-color: #000; color: #FFF; border: 1px solid #A60000} (Can be customized of course)
#surprise {display:none;}
Then add to the forum's wrappers:
<script>
if ($('.myTestAd').height() == 0) {
document.getElementById('please').style.display = "block";
document.getElementById('surprise').style.display = "block";
} else {
document.getElementById('please').style.display = "none";
document.getElementById('surprise').style.display = "block";
}
</script>
Important note - I have whipped this code up off the top of my head... I have not tested it and it may require tweaking to your exact specifications. Therefore any use of it is done at your own risk.
So now if they turn off javascript entirely the forum disappears and they get a message asking them not to disable ads/javascipt. (If they just disable the ad then they get a message asking them not to block ads.) Sure they can still get around it, but it means disabling javascript and using their own CSS patches.
Still doable for someone with some knowledge, but for most people it's likely just easier to enable the javascript/disable the ad blocker on that site.
I do run my own ads too and I understand the pain of people blocking them. But I also understand why people block them in the first place. (Sometimes it's a security reason in that some advertisements carry viruses and other malware that slip through the ad-networks filters. Or it's a health reason in that flashing lights of some ads can trigger epileptic seizures. So it's not just because people are thieves or don't want to see ads... Though that can also be a part of it.) A better idea might be to have a donation box of some sort so people can give money to the site directly and be given an ad-free view.
