Edit: sounds like this is what reddit does. Props to them!
I believe they all used https://www.projectwonderful.com/ as their ad provider, by the way. I haven't really inspected them, but if you want inoffensive ads on your page, that might be a good place to start looking.
It seems to be very heavily used on webcomic sites I frequent, and I haven't seen a bad ad yet.
I also like the idea of purchasing time on a site, rather than using targeted ads. Meanwhile, the hosting site can discontinue the ad if they feel it doesn't match their culture.
It's more analogous to renting a billboard from a friendly business you like, rather than hiring a bunch of people to follow your customers around with posters.
It just seems like a stand-up way to do ads.
The HTTP DNT process at the W3C was supposed to fix this, but it got derailed by the DAA (the Digital Advertising Alliance).
You can manually stop this tracking with AdChoices. Click on that weird little blue icon that's in most ads, and you'll be able to disable tracking by DAA members.
Notably, AdChoices doesn't entirely prohibit tracking - I think you just need to be "minimized" to a certain extent. AdChoices is stupid, but it looks like we won't get a real solution in DNT unless something changes within the next month or so.
I, as a user, wouldn't be happy having to blacklist all sites.
I won't pay a monthly fee for most sites, because I read a little on a lot of sites - I don't mind paying a 1 penny per article fee if it is convinient.
I guess PageFair additionally lets you collect statistics on how many users are blocking ads, which may be useful.
