CERTAIN sites, who shall remain nameless decide to limit your access to reading say a certain number of pages per month/week/day.
Then they demand cash to read more. They do this by setting a cookie in your browser.
If you edit your cookies and delete the ones from that site, that resets the counter and you can read as many as you like.
Since you have no contract with the site, and since no one has yet argued that editing your cookies is illegal, its hard to see that any laws are being broken.
Likewise if you choose to use adblock or flashblock to remove the more egregious paid adverts and googleanalytic crap..
I pass this on in the interest of cost effective browsing in the community...
