As someone who's been fact-checking a lot of the stuff I see on the internet for years, I love the idea.

The overall ratings by the algorithm seem pretty solid to me, and the explanations are very helpful for understanding the thought process behind the scoring.

That being said, some of the points in the "dubious" section seem a little questionable in my opinion. For example: "'Applicable to US customers only.' Reason: This is a marketing tactic to get US customers to sign up." This doesn't seem like a marketing tactic, I think this is just relevant, factual information.

Do you have a strategy for tweaking the algorithm for things like this?

Maybe you could add an option to provide feedback on the points in the breakdown. Either a like/dislike system or just a "report" button with a prompt for optional feedback.
