第二篇：   As social media websites grow, concepts of privacy seem to be changing. Images and information that would neverbefore have been public are now available at a keystroke. For some people, the free-floating information is harmless. Forothers, though, it can be embarrassing, annoying, or even a matter of life and death. Recruiters now regularly perform Internetsearches on job candidates. Cyber stalking has become a real and dangerous problem. While it used to be relatively easy toturn over a new leaf by moving, now the Internet can prevent anyone from really starting over.   In these cases, there is the option of erasing one’s web presence. Social media sites are often the first step. The websitewww.sucidemachine.org offers a simple process that will eliminate your accounts from four social media sites.    Those sites are just the beginning. If you’ve ever written a blog, created a photo account, signed onto a mailing list,gotten a cell phone, or done another thousand things that end up on the web, you’ll still be searchable. To delete theinformation that the Internet holds, first you’ll have to find it. Social aggregator sites like Pipl.com and Spokeo.com listaddresses and phone numbers, as well as other information. This information can be deleted by specific request. Searchengines will often remove you from their results if asked.   However, information can linger in hidden places only to emerge later. To be thorough, some people employprofessionals to do a web deep clean. Reputation.com and removeyourname.com are two companies that specialize inimproving online reputations. Often, this means removing as much information as possible and then burying bad informationthat can’ t be removed with new, or good information.   Removing your web presence can be painstaking and expensive. Perhaps the hardest part about cleaning yourself off theweb, however, is staying off it. So much of life is conducted online now; we may never be able to completely private again.
