Interesting case this, concerning use of multiple logins from a single account:-

The Financial Times (FT) is suing a company it accuses of using one access account for many users. The FT claims that investment group Blackstone encouraged staff to dodge the cost of multiple subscriptions to its services.

The FT's action is based not just on the number of articles accessed under the account, whose username was theblackstonegroup and whose password was blackstone, but on the digital traces left behind at its site by the different instances of access.
