Companies including the one I work for in the past requested new applicants for employment the password for their Facebook page to "review" the postings and " attitude" of the person.
Well guess what? Company's no longer need to ask the perspective employees for the password. Facebook does sell access to the pages regardless of the security set by the user. Companies are using social media to do "background" checks and the user thinks because they don't ask the company does not check anymore.
How many people bother to read fully the service agreement before checking yes!.
Most don't even realize the service agreement contains a Data Policy agreement where Facebook can and does share information with Vendors, service providers and other partners. they agree not to disclose your info but seem to be free to use it for their needs. Translation = Employee hiring.

SO now do you think WhatsApp is so secure? I tend to agree with aiharkness in that caution is needed with any personal info.
