With respect, I regard that article as an a successful attempt by FB to dupe the BBC into providing free advertising, coupled with the fact that those who are drawn towards social media tend, on the whole, not to be terribly IT savvy. As the song lyrics go, “any publicity is good publicity”.
In my case, I joined FB as a means to an end, to participate in a reunion of old colleagues. I never posted any info on FB, nor did I receive any. Interesting then, that an attempt should be made to hack such an account?
