in his article, Penenberg report that he challenged Dan Cohn of Docusearch.com, a Web detective agency, to get as much information about him as he could. It didn’t take Cohn very much time before he could report back to Penenberg with almost all the information and secrets Penenberg would not tell anybody about. This is really scary. No one can feel secure if their personal private data that they used to get some services can easily be given to somebody they don’t know and without their permission. What kind of privacy do people still have then? In addition, your personal information can be used against you. You might find yourself bankmpted.
