Pagefair is basically "Clean ads as a service." If they detect your using Adblock plus, they'll server you an ad, adblock plus won't block, because they pay adblock plus. (And because they claim to follow adblock plus's policy of 'good ads').
Which is annoying, because if you aren't using adblock plus, you don't get decent ads (just the standard ads), so ultimately it defeats the goal of adblock which is to make all ads non-obtrusive, for all users, not just the chosen few who use adblock.
Adblock edge will block pagefair ads, because adblock edge is a not-for-profit adblocker, unlike adblock plus.
Also hosts blocking remains a completely viable option.
That thread links to a page that uses PageFair. After enabling a bunch of JavaScript domains (what, you're still not running NoScript?), an ad does indeed show up:
Rather hilariously, the ad is for a "Free Mp4 Player" and links to Ask.com or something. If this is PageFair's idea of the future of quality advertising, I don't think their company is long for this world.
There was an ealier story in new about pagefair cleaning 600k in funding. I idled slightly and read their FAQ's while waiting for a tests bench to get set up.
It's interesting, I imagine they'll be sucessful, and it will ultimately drive up hosts blocking again (I do this, hate no script, I like my website's shiny chrome).
Adblock Edge is included, as is every plugin or proxy that acts to remove advertising from web pages. Unfortunately, we can't specifically distinguish adblock edge from the others right now.
