I'd recommend trying a 3rd party fraud scrubbing service.

Stripe's Radar is all well and good, but they have no skin in the game. If they're right or wrong, you're on the hook.

Services like SIGNIFYD apply their own fraud logic. If a transaction is approved and is later disputed, you are refunded the value of the order and the chargeback costs.

Not associated with them, but have been using them for several years and hundreds of thousands of transactions; our fraud problems are non existent.

Although in that case isn't SIGNIFYD's 'skin in the game' that they're on the hook for fraud so they're incentivised to be overzealous in blocking?
