there are still out there a lot of sites that earn their money throught adds and thats why they want you to dissable your Adblock even to be able to get in the webpage. I personally just dont open this sites and search for an alternative one, that maybe could give the same information that I am searching (in other online newspaper for example), but without this annoying messages. If you really wan to visit these pages, you can click on the uper right corner of the browser on the Adblock red symbol and there allow the adds for this site. You will need to refresh the site and you will be able to visit this page.
Hope it helps,
