hacking is commonly used to mean different things, and we imply from the context what the author really meant. Do any lawyers know if computer hacking has a legal definition, or if this decision will lead to a specific legal definition of the term?
I think it was last year that facebook went after fake likes / fake followers companies who were logging via the login page and they liking / following. Companies in China / New Zealand and I think NY? got threatened with the CFAA (unsure if it went further) but it made the tech news at the time.
I don't think anyone hear would call writing a bot that logged in with actual details and performed an action (the same a real person could) as hacking, but facebook were saying as it broke the TOS, it was unauthorised, thus hacking laws apply. With their budget, I guess they get to decide what hacking is
