I think its fine that it was moved behind a secure login and rate limited - because there's other information that's useful for identity theft and/or stalking (date of birth and municipality - along with a history of re-locations - not at address level, but specific enough that it poses a great de-anonymizing vector for a (working) population of ~3(?) millon. A simple name+city lookup would normally be enough to look up date-of-birth).

But now they've added a "shame"-filter of alerting who you look up -- which makes some sense, but IMNHO removes the democratizing effect a bit. Before, you could look up the salary of the person(s) interviewing you for a job, along with salaries for various people in the company (assuming a public listing of employees, which is normal). You can still do that of course, but I'm afraid too many will be "offended" by this way of using information that's public by law to reduce the information asymmetry. The flip side is that a potential employer can also see what you've earned the past few years.

I don't think most people used it like this though - it's useful for checking what public figures earn/pay in taxes - and it's useful to do a rough sanity check to see if work place agreements on compensation are followed (there's no minimum wage in Norway, but unions are still strong) - and also to do a rough check for gender imbalance in salaries at a given workplace.

You can see what kind of salaries people get in same kind of jobs.

I wonder why nobody gives up his good name for a crawler.
