Available for Internet Explorer and soon, Firefox, BreakThePayWall works mainly by deleting cookies sites use to limit the number of stories users can read before having to subscribe. Deleting the cookies means the publisher’s site forgets how close the reader is to the “pay up” threshold.

In theory, it could be a challenge to those that use Google’s First-Click-Free scheme, which publishers can use to let searchers read only up to five articles per month before subscribing. No BreakThePayWall user numbers are available and the hack seems unlikely to severely impact publishers’ strategies because it has not gained widespread attention on the web.

But it is a clear response to the recent re-emergence of paywalls and may prompt proprietors to think of new techniques. It’s basically a sign of the times.

Web users can already employ the same technique by manually deleting cookies in their browser; BreakThePayWall just tries to make it easier.

“The paywall thing came about because of our annoyance at how easy it is to get around them,” BreakThePayWall’s developer, who did not give his name, told me. “Lots of compromises are made and basic security not adhered to. The utility currently uses cookie and referrer techniques - we have not come across any other techniques… yet.”

BreakThePayWall is thought to have piqued the interest of FT.com, which uses First-Click-Free to give five free articles per month to Google (NSDQ: GOOG) searchers.

The developer is also working on a hack that lets users more easily claim compensation for train delays.
