Doesn't the EU lean towards privacy protection for individuals? I'm assuming Sweden being a member, means that EU laws would take precedence if someone wanted their information removed from websites like these?
Not Swedish, but the relevant one in the parent comment is probably mandatory residency registrations, and I'm surprised the data is so publicly accessible there. There are usually attempts at creating firewalls in many countries so the data that one agency collects isn't directly linked to that of other agencies, preventing broad files on individuals.
