Earlier quoted context omitted.
That particular example may have been exaggerated or extreme, but I think the point still stands. Someone just commented this "check out flat earth videos... they remove all comments that are critical and now with the dislike counter gone i guess the earth is flat.". Indeed. In this case for example it should not be flagged, but down-voted by the community.
I honestly couldn't tell whether that flat earth comment was being ironic or not, but I think it's an interesting case study either way. Is a visible YouTube downvote count really the only thing standing between a meaningful number of people and belief that the Earth is flat? I don't really buy it.
I do not think so either, to be honest, but perhaps there may be something to it.
