The Financial Times is suing Blackstone accusing the US investment group of deliberately encouraging its staff to share a single login to the FT.com website in order to avoid paying for multiple subscriptions. The FT claims a single FT.com account was set up by a "senior employee" in Blackstone's finance and compliance team in 2006. By 2008, the FT says the login had been used to access "thousands of individual articles on FT.com, far more than any individual would normally access". In addition, the FT claims that by tracking Internet Protocol (IP) addresses and other computer identification techniques, its findings "point inescapably to widespread use of the single, individual account on FT.com by many different persons." FT.com logins cost between $179 and $299 per year for US users.
