Yeah great point, personally I already assume the worse as far as how much information is accessible to them. What they do with it is where we really don't know. I know you can find just about anything on the dark web ;)

Even in other circles there's probably more of our information being sold depending on what companies/gov projects need. Just look at what's happened to Facebook - there are some employees that left after realizing they created a monster of algorithms through the use of our divulged information..
