How can you stop a website from displaying personal information and where/how can you file a complaint against them?

ZabaSearch.com claims that it is only displaying information in public records. However, several people have complained that ZabaSearch is displaying private information. (See: www.consumeraffairs.com/online/zabasearch.html)

ZabaSearch charges money to not display one’s private information which seems to be a form of extortion.

I am interested in learning how one can stop a website from doing this and where/how one can go about filing a complaint against this company?

My guess is that one could start with the FTC and the BBB. What other guidance can you offer?

Thank you.
