It is digital surveillance. I could mine all your opinions from 7963 posts. Find those subjects that trigger a nervous or anxious psychological reaction or subjects that produce bad sentiment. Find out your sleep cycle. Find that one post from 2013 which you have now forgotten. Do the same for the account you most replied to. And then serve you catered (political) ads that are incredibly appealing to your deepest emotions (I was able to heuristically match your laptop with your smartphone, the only part that needed some luck). Or use that information when I am investigating you (with or without reasonable suspicion) or interrogating you (for a death penalty crime with an estimated 4.1 percent of wrongful convictions). But that would be digital surveillance and I have no reasonable suspicion to surveil you.
