But you’re saying yourself that those are “obviously bots”. It’s easy to ignore those. And just to be clear, I really did mean the reviews, and not the score (where the skew is less transparent).

Everyone leaving a review has to have an account somewhere in the federated network. This includes seeing up an instance just to use it for review bots, or fake votes on something. Obviously there’s is defederation and other mechanisms, and I’m sure there are ways to improve the situation. But the whole base setup is just inherently much harder to get into a trustworthy position. Even the common centralized sites (not just Amazon) have trouble getting it under control when they can “see” will the related data, for finding outliers and such. I’m just saying it’s an even harder proposition.
