Advertisers may want to track everything, but that doesn't mean you have to. If everyone is doing it, you can differentiate by saying NO.
As a marketer my problem never was "I don't have enough data", but it always was "I don't have enough traffic". Give me quality traffic and I'll hand you my money.
As a publisher THAT's what I want to offer. Quality traffic, without all the bullshit.
Maybe that gets me 10% of the revenue that all scummy 'best practices' get me, but I think it will work out great in the long run.
I only need an ad network to facilitate this, without having to set it up myself.
