Individuals have all sorts of perverse incentives. Politics can inspire a good few examples here. But, off-topic.Individuals do not have a direct perverse incentive to deliberatly inflate review scores the way game critics do
It’s not remotely comparable
Individuals don't have the same incentives, and the standards a publication is (or should be) held to should be greater than any single individual. But they exist.
(though it's also not impossible for a user to be "bought" - this is why Steam factors both gifts and refunds into review status)
Ironically, discrediting any publication based on allegations that surround one, or even a handful, is also itself an off-topic tangent. So it's difficult to explore constructively in this subforum, which is why I'm happy simply making the point that "trust" is a subjective metric that applies to both critical and user reviews.
