Here’s The Thing With Ad Blocker detection code.

I get it: Ads aren’t what I'm here for. But ads help the site keep the lights on. So, I've added your site to my ad blocker’s whitelist.

So why are you still showing me the adblocker warning message and preventing me from reading your content?

Could it be because I've got doubleclick in my /etc/hosts file pointing at localhost because I don't particularly want doubleclick and google tracking everything I do, everywhere on the web. Can't your adblocker detection code tell the difference?

Oh well. That's another site I'll try and remember not to click through to.

So what do the common adblocker detection libraries actually look for?
