Twitter has sold billions of archived tweets believed to have vanished forever. A privacy row has erupted as hundreds of companies queue up to purchase users’ personal information from the new database.

­Every time you use social networks you become mere product – it’s an idea we will all have to get used to. So, should we give up worldly goods and hide in a Tibetan monastery till the end of our days, or start putting up a fight to protect our privacy? In the latest in a long series of scandals over social networks that profit from our private data, the UK-based DataSift firm has announced that is has bought every tweet posted since January 2010. The business intelligence and data-mining platform will be the first company to offer the archive for sale.

DataSift’s Historics is a cloud-computing social data platform that enables businesses to extract insights and trends that relate to brands, news, public opinion and … actually anything you could ever need… from Twitter's public tweets.
