What would actually make you trust a free stock-risk score?

I'm building PumpProof, a free tool that reads a hyped stock's SEC filings and scores its pump-and-dump risk from 0 to 100, with every flag linked to the source document.

The hardest part hasn't been the data. It's trust: why should anyone believe a risk score? My answer so far is receipts, every score is public and dated the day it runs, wins and misses, so you can audit the record instead of taking my word.

But I'd genuinely like this community's take: when you see a "score" or a "risk rating" on any product, what makes you trust it versus roll your eyes? What would you need to see before you believed one?
