Guys like you just contribute to adblindness of our visitors. If I would click on an Ad, then get to a page with more ads, where I click again, just to get to another page with ads ... I would eventually never ever click on any ads again.
So I run the occasional campaign to get a few more visitors to my information site and I'm suddenly public enemy #1?
I mostly opt out of content advertising, and it's clear the ads are for an information site. I guess the biggest surprise is that any visitors that click my ads actually do find an information site (as advertised), as opposed to the usual crap youi get when you click an information site advert.
