Personally I don't care if it drives guests away. I would hope they would register where they would not be blocked from blocking ads. If they are registered then it is my hope that they would become active in the community instead of just being lurkers.

However an unregistered user blocking ads on my site lends nothing to my site the only thing that it does for me is costs me money for their bandwidth, so if they go I am not missing out on anything.

Again I want to block people blocking ads from displaying showthread.php, and given the option to turn off their ad blocker software or register and become a member where they can use their ad blocker software but then again when they are registered can hopefully become an active part of the community.

Guest blocking ads lends nothing to your community, they only cost you money.

Ok I think I have found out how they do it and the javascript used.

Now to figure out how to put it in so that if a unregistered guest has ads blocked and tries seeing a thread they instead see a message asking them to turn off their ad blocker or register.
