If a foreign government agency had spent years gathering data, and was mining it for undisclosed (possibly nefarious) purposes, It would be known as a dangerous spy network, would be subjected to infiltration/corruption and possible attack.
I completely fail to understand why people tell FB anything about themselves ever, and don't request immediate deletion of all the data held about them.
When governments try and spy on someone, they get all upset about it, when FB does it, and freely allows the data to be sold to the highest bidder/anyone who cares to look, people think its really cool and useful.
what does it take for people to say enough is enough? Is it too late now, since the data is already gathered? why do I fail to see the upside of FB and its data gathering ilk?
