Happy to share their responses verbatim. It was a rather long back-n-forth. Here's a snippet from the latest email, which I think makes it clear that they do not use the evidence I provided:

    I can assure you that I will take note of your feedback and pass it to our team. Your point about post-transaction abuse detection is valid - while Stripe has robust network-level fraud detection, there does appear to be a gap in utilizing merchant-provided evidence of confirmed fraud to protect the broader merchant ecosystem. This type of feedback from merchants who have direct evidence is valuable for improving these systems.
