content: I first saw the "We see you're using an adblocker, please turn it off for our 'ad-light' experience" message a few weeks ago, so it's been in alpha or maybe beta for a while. Then about 2 weeks ago (shortly after I first saw the banner) there was somebody who linked to FuckFuckAdblock which requires GreaseMonkey (or a similar extension) to run, but completely negates that banner in a way that can't be circumvented.
