Governments and mega Corp have some level of responsibilities. If someone is judged illegal, irresponsible, they can be prosecuted somehow. You have some limit to their power and some restrictions to what data they are allowed to gather and use, even if it practice there is obviously some issues at this level.

What the OP suggests is to use the power of the mob to apply surveillance to potentially anyone, completely removing the concept of privacy. That sounds incredibly dangerous and nefarious to me.
