I stop visiting websites that prevent me from seeing any content if I'm using an ad blocker. Wired, for example. I was never an avid reader of Wired but they do publish some interesting content and I would find myself reading maybe three or four articles a month. Since they made it clear that people blocking ads are no longer welcome on their site I stopped clicking on Wired links.

I know there are ways around such blocks but I don't bother using them. If a site prevents me from seeing its content if im blocking ads I close the page and make a mental note to not click on links to that site anymore.
