Disagree that specific forums are more trustworthy than others. To me, a trustworthy source is a known entity that tests themselves and keep a track record of accurate reviews. For specific forums, keeping track of users that post honest reviews would be a good way to start.

> Fake reviews are certainly a big challenge, even for companies like fakespot that try to detect them.

Not that big: If you cut away all 5 and 1 star reviews you'll have stripped roughly 99% of astroturfing (for and against a company).

How do you figure either HN or Reddit (anonymous, unverified accounts) are trustworthy when there’s money to be made by astroturfing? The incentives are stacked against you.
