The only way of being anonymous in Sweden is illegal?
I knew a software engineer who used to live in sweden. One day he had a payraise. Out of the blue his landlord raised his rent. Apparently she somehow found out about his payraise and now i know how. She even told him that she knows he can afford more. He left sweden for this reason and racism. Before you believe all them nice stories about scandinavia, be sure to talk to people that lived in any of those countries as they all have some very disturbing practices.
