Detecting Adblock

[mrbene]

Looking through some old forum topics over at [url]aasted.org/adblock[/url], I came across the Javascript element window._AdblockFiltered. It's supposed to be an array that has a list of blocked elements in it, but I haven't been able to get anything other than "0" using window._AdblockFiltered.length.

As proof of concept for detecting Adblock, I used:

Code: Select all

if (window._AdblockFiltered)
    {
    alert("You are using Adblock to block ads")
    }

This only works after page element has been blocked - if no element gets blocked, this array doesn't exist.

Anyone done anything with this, seen anything done with it? [/code]
