One of the problems with relying on user reviews to assess content is the possibility that some of these reviews may not be written in good faith. Recent rat tomatoes took new steps to address the consequences of false reviews submitted to Captain Marvel while Netflix responded to several cases of "review bombing" by completely removing written reviews from their service. Over the years, Steam has taken several steps to address the problem, but now the latest answer is a combination of automated scanning and human moderation teams.
In a blog post, it explained the plan: "We will identify bomb investigations, and remove them from the review results." In practice, it is a tool that monitors real-time reviews to detect "anomalous" activity that suggests something is happening. It warns a team of moderators, who can then look through the reviews that will investigate, and if they find that there is a plethora of "off-topic reviews", then they will warn the developer and remove those reviews from the road game's points are calculated, even if the reviews themselves will stay up.
