Any information held on the Internet can be theoretically saved indefinitely. Google allows you to search through Usenet discussions back 20 years, news articles from the last 200 years, and for its 10th anniversary, allowed users to briefly search its saved cache of the Internet from 2001. This is compounded by the privacy policies of some social networking sites. Facebook, for example, does not allow a way for users to entirely remove an account; it can be deactivated, but the information about you will still be saved on the servers, and is accessible to the company that runs Facebook indefinitely.
