How to be left alone?

Value your privacy as much ? Sign up for the do-not-call list. Many of them do that with th’r landlines, but you can put your cell phones on the list too. The Federal Trade Commission’s Web site links to www.donotcall.gov, where you can register up to three phone numbers at a time. Stop getting those pesky Pre-approved credit card or insurance offers in the mail by calling 1-888-5-OPT-OUT or by going online at www.optoutprescreen.com. Unless you change your mind at a later date, the restrictions are in place for five years. You’ll save some trees and reduce the chance of someone using the mailing for identity theft purposes.
The Direct Marketing Association also maintains listings of consumers who prefer not to receive mail or telephone solicitations. The DMA can provide information about opting out of lists produced by companies that subscribe to its Mail and Telephone Preference Services. There’s a nominal charge to request the service online, but it’s free if you mail in your request. Visit its Web site for more information.

Thanks to bankrate for the info.
