In the The Orville episode "Majority Rule", a person who receives a million downvotes is arrested and, if the final tally tops 10 million, subject to "treatment". During an apology tour (and at other times), a person can be upvoted or downvoted by, it would appear, anybody who encounters him or has his badge number.
These triggers are expressed in terms of the number of downvotes, and from what we see in the episode it's clear that this is an absolute value, not downvotes net of upvotes.
What function do upvotes serve? Is it just that each upvote represents someone who didn't downvote, or do they do something else? I'm wondering about a hypothetical person with 10 million downvotes and 20 million upvotes -- does he get treated too?
