So the local newspaper I readno added a paywall to their online site. You are no limited to 20 free articles per month. Then you have to pay to read on. Anyone here will probably instantly ask them self: How do they control how many articles you have read?
I use no-script so first I realized when I deactivate one of the scripts, the paywall is gone.The paywall i nothing else than an obvious nicley styled JavaScript pop-up that informs you how you can pay. Once you close it you are redirected to the main page (on which you can read all the headlines always). The downside of disabling that one script being that some content including images and user comments are then not visible and you can't write any of them. All in all the expeirence was still very much usable.
So with firebug I looked at the request

which contained tons of cookies. I guess you can see were this is going. Simply deleting all the cookies makes the paywall go away. And the next step is to block them in the first place. Win. Free again
