Blockshopper.com has begun posting personal information. They have posted home addresses; sales price; pictures of people, homes, and children; listed occupations and employers; the names and addresses of neighbors (with links to their page) in one place and available just by searching "a name". They will not remove as they say all information is public. This is done not for real estate purposes. They are using names without permission to advertise their business and make money from AdSense and advertisers. They gather information from public records and through the web, including social networking sites.
