After searching Google and Stackoverflow for a few hours I could not find a solution. What I\'m trying to do is detect Adblock plus and display a simple message for now.
I have found one of the best scripts if you use third party ads.
antiblock.org Disclaimer I'm not affiliated with this site in anyway.
It will work for most sites and if they want to bypass it they will have to add their own filters (complicated for normal users) or contact adblock filters and have one added but they quit doing that cause the list is getting over loaded and slowing down ad block users.
