Nah -- we're not there yet.
Having the capacity to store data is one thing, but actually physically responding to some offending post or remark is another. That requires an individual agent, investigator, or whatever to put down their donut or their pastrami sandwich and physically go check you out, which they don't wanna do because they're more worried about fentanyl traffickers than they are some right or left-wing internet troll.
That's not to say we couldn't get there. China has set up a pretty sophisticated surveillance state by requiring the installation and use of government-monitored spyware in every communication device. They are also constantly collecting all kinds of biometric and location data on individuals - like all the time.
If the U.S. were ever to become a one-party state, then that's when we enter dystopia.
