Stripe checked who this person is before Stakk let them take a payment.
Stripe checks a person's details against a government ID or trusted records. Every Stakk creator passes it before their store can take money.
It has safeguards. It does not prove someone is who they say they are.
It says nothing about what they sell. Your payment goes straight to this creator's own Stripe account - Stakk never holds it, and their refund policy is theirs.
