I would mention hitta.se from Sweden. Probably a privacy nightmare to some, and very creepy to others.
On the page you can search peoples home address, phone number, date of birth, other members living in the same house, real estate value, mortgage rate, all by searching their names. I successfully once identified a parent of a owner of a lost wallet, only containing a gym card with last name on it. Found her phone number on the site, called her and gave her the wallet.
