Steam now has "language-specific" review scores, which might make identifying certain review bombs easier
Review scores. Who needs 'em? Well, Valve reckon Steam didn't have enough two word verdicts on games, so they've introduced a "language-specific" scoring system, which offers separate ratings based on user reviews penned in certain tongues.
The goal's to paint a more detailed picture of what folks in different parts of the world think of what they've played, allowing you to see at a glance whether that game you've been putting off adding to your backlog is the bees' knees among Korean-speaking players. That's provided said game meets the threshold of having 2,000 publicly visible reviews in total and at least 200 written in the specific language you're looking for.
