TrustPilot lacks Trust
To stop fake reviews and scams, TrustPilot does a massive amount of browser fingerprinting and heavy analysis of phone numbers, emails, and IPs. And they even insert spyware on the vendor's website, to do surveillance if the traffic/buyers are real.
But in the end, can you even really trust TrustPilot reviews? Because if someone criticizes the product, the seller usually finds some way to dismiss their claim.
Compare that to our system with PGP receipts, Nostr, and crypto deposits with an arbitrator nostr:npub1ajlljavyzaj44k96zg7euzxkp4m8q3w6yfrjah5xel4gax3v697qc5d9u3. If anyone actually complained about being scammed out of a phone, they'd have cryptographic proof. And with Nostr's Web of Trust, it's pretty easy to see if it's just me on a burner keypair.
