I know some people here have Web sites, so I wanted to share my latest way to block and/or annoy Adblock Plus / Adblock Latitude users.
All this is a simple PHP script that opens three nested divs with IDs selected from Adblock's "EasyList" subscription. The script should be included in the PHP code at the beginning of the content you want to protect. You will also need to close the divs at an appropriate place on the page.
For example, if you use a common header and footer for all your pages, you may want to insert the script at the end of the header, and three </div>'s at the beginning of the footer. That would allow the header and footer to display, but nothing in between, as long as Adblock is enabled.
Here's a demo page: http://www.rjmsandbox.com/ABP_Blocker/ . Try it with ABP enabled and disabled to see the difference.
Here's the script:
Here's the code for the demo page:
To make it extra annoying, the three div IDs are randomly selected each time the script runs, so every time the user opens another page, he would have to disable the filters all over again (or disable Adblock altogether) in order to see your content.
The IDs are selected from three text files populated with banned IDs selected from EasyList. Look for the entries beginning with ###, copy three handfuls of them to text files, Remove the ###s, and separate the entries with tildes. Then save them as ab1.txt, ab2.txt, and ab3.txt.
Here's one as an example:
You can see the other two example text files here and here. Any handful of banned div IDs from EasyList can be used, however.
