Would this change mitigate the problem of clickbait scores on Metacritic?

[Pachofilauri]

Yes and no. If a game has 20 reviews with a score of 100 and 1 or 2 reviews with a score of 60 or below, its obvious that the those are the click bait reviews. This also works the other way around where the high review in a bad game count as a click bait or "paid" review
