Well... let's say you're a politician wanting to regulate Facebook, and let's say you have an affair with whom you communicate on Facebook or in Instagram DMs. If I were Facebook, I'd simply let an investigation team check if any dirt can be mined out of the troves of data - anything, even the dataset of GPS or other location pinpoints, can be enough to get a first hint. And now I discretely contact you and advise that there may be information around and that it would be a pity if that information were to get public.
This is the ultimate problem with the size and capabilities that companies such as Facebook have.
That's Dark and Illegal
Is this really a threat any longer? I mean, Stormy Daniels, $130k payoff pre-election, etc and all...
