I was wondering about this the other day and thought someone here might know. How does one even determine if an ad blocker is running?

An easy way to detect is to see if an ad div is visible and > 0px tall.

Edit: Clarification: Most ad blockers collapse the divs where ads would have appeared. That's the tell I use to detect ad blockers. There are other, more sophisticated techniques but this is easy and works a good % of the time.

I suppose the next question is how does the ad blocker detect circumvention techniques?

If you have experience in this I would love to read about some of it as it sounds fascinating.
