I just came across this wonderful piece: Scroogled by Cory Doctorow
“The courts won’t let them indiscriminately Google you. But after you’re in the system, it becomes a selective search. All legal. And once they start Googling you, they always find something. All your data is fed into a big hopper that checks for ‘suspicious patterns,’ using deviation from statistical norms to nail you.”
and I think it is a must read for all of us. And that’s besides it being an entertaining read.
