This is not Black Mirror. This show was way before Black Mirror.
People were liked, disliked, or ranked in some voting system. If they got to many negative responses from population they were sentenced to death. I believe one character was first arrested for making a negative comment about a statue or famous person of that population/dimension.
Not way before Black Mirror, but could it have been "Majority Rule" of The Orville? Seems to hit all of the details.
In a police station, LaMarr sits before Publicity Officer Willks, who explains that LaMarr's slew of downvotes come because his suggestive dancing on a statue of a Sargun hero was recorded by others and uploaded to the Master Feed, an online video and voting platform. LaMarr had surpassed one million downvotes, which made what he did a "crime against the State." LaMarr was arrested and must go on an apology tour, several live television appearances that will be judged by the public for his sincerity by voting in the Master Feed. If he accumulates over 10 million downvotes by the end of his tour, he will be forcefully corrected via a neurological readjustment called Social Correction.
