Ad blocking plugins like Adblock Plus are one of the most popular addon fors browsers today. However these addons deny publishers revenue to operate their sites.

One way to force users to disable Adblock is to deny them site content until they disable adblock. The following template modification is the vBulletin implementation for the antiblock script from http://antiblock.org/ . This script will prevent users from viewing thread content and ask them to disable Adblock.

Implementing this hack is very easy. In your style manager select the style that you are using and open

Show Thread Templates > SHOWTHREAD

In showthread go to the bottom of the page and just before

HTML Code:

</body>
</html>

That's it. :)

The code is for v2.0024 and may be updated as adblock develops countermeasures for it.
