Facebook users are dumping 'friends'
Users of online social network sites such as Facebook are editing their pages and tightening their privacy settings to protect their reputations in the age of digital sharing, a new survey shows.
About 63pc of users questioned in the Pew Research Center poll said they had deleted people from their "friends" lists, up from 56pc in 2009.
Another 44pc said they had deleted comments that others have made on their profiles, up from 36pc two years before.
Users also have become more likely to remove their names from photos that were tagged to identify them.
"Over time, as social networking sites have become a mainstream communications channel in everyday life, profile owners have become more active managers of their profiles and the content posted by others," the report says.
