> To expand its user base, Power asked users to provide their Facebook credentials and then—with their permission—sent Power.com invitations to their Facebook friends. Facebook, naturally, didn't appreciate this marketing tactic. They sent Power a cease-and-desist letter and also blocked the IP addresses Power was using to communicate with Facebook's servers.
> Facebook sued, claiming that its cease-and-desist letter made Power's access unauthorized under the terms of the CFAA. Power disagreed and argued that having permission from Facebook users was good enough—it didn't need separate approval from Facebook itself.
How can be illegal if users are giving their permission? What happens if I give my permission to an external service to extract my own data?
