Interesting to see how others are doing this. I recently was tasked with adding some logic to determine the number of ad-blocking users across the network of sites I help maintain. I added my own custom script into Appnexus (ad provider) and attempted to load it. Ad-blockers, I discovered do one of two things in this case. The first is to just block the loading of the content, in which case it was easy to detect. Others would inject their own custom content, hence adding a custom script and then checking the contents for a special string. A fun task for sure though.
