Facebook has sued a Brazil-based web company that allows its users to connect to a number of social networking sites at once.
It claimed that Power.com violates laws on copyright, trade marks and computer misuse. The site allows people to receive and send information through the site to a number of social networking sites including MySpace, Orkut, MSN and Facebook.
By logging into Power.com and giving their username and password for each site, Power.com can retrieve and post information automatically.
Facebook has claimed that the use of the subscribers' accounts is unauthorised, that the system sends spam to other users, that the use of the Facebook computer network is unauthorised, and that the system infringes trade mark rights and copyrights.
Facebook also said that it has a platform by which third party developers can integrate software with it, called Facebook Connect, and that Power.com should use that.
Power.com said in a statement on its website that it is working to create a new version of the site by late January that uses Facebook Connect. Facebook said in its lawsuit that it did not want third party sites holding username and password information.
The social networking site said: “Facebook is dedicated to protecting the privacy and security of its users. Facebook tightly controls access to its network, and implements a variety of features in order to protect the privacy and security of its users' personal information. One such security measure is the prohibition of soliciting or sharing user login information.
“[Power.com] has knowingly and wilfully disregarded Facebook's protocols and procedures for accessing information stored on Facebook computers and is offering a product that solicits, stores, and uses Facebook login information to access information stored on Facebook computers without authorisation and to display Facebook copyrighted material without permission”.
The lawsuit said that Power.com chief executive Steven Vachani said in December that he would change the way that the site worked and use Facebook Connect within two weeks – the deadline for which was 26th December.
Facebook said that it received a subsequent email from Vachani saying that it would remove all infringing integration whether or not it had implemented Facebook Connect by 26th December. It said that Vachani then told it that Power.com had taken a ‘business decision' to continue the integration until it could implement Facebook Connect.
