Are there no murderers, crazy ex-boy/girlfriends, targeted harrassment and spam calls in Sweden?
Not that any other country does much better in this regard. Still it sounds a little wild to me that you can get this information without even needing to hit a shady forum and download some csv. Maybe lowers the bar too much.
There are. You can get a protected identity if you have that issue.
The current system has been in place around 1770. There's some pushback against it the last few years.
I've been told back in the day it was quite normal get a physical, dead-tree book with similar information sent out to you every year, until people decided that was a waste of paper.
