A while ago Steam introduced so called "off-topic review activity" which is described as follows:
On products where you see this symbol next to the Review Score, we've detected one or more periods of off-topic review activity. In those periods, where we believe the content of the reviews is largely unrelated to the likelihood that you would enjoy the product, we exclude the reviews when calculating the Review Score.
SUPERHOT VR is one of the games where Steam notes this "off-topic review activity" after the developers cut content (main story elements) from the game, years after release. In my eyes this is equivalent to censorship of valid, but negative opinions which artificially raises review score of a game.
Since Steam offers real review scores to users who explicitly opt-in. I believe that gg.deals should provide the same option to display (and filter by) actual Steam review scores, rather than the censored version that's presented by default.
