I was on Stripe Radar's free trial, but it wasn't as effective as I liked - it also turned out to be very pricey paying £0.04/screened transaction. I've now rolled my own combination of IP-based bans on creating checkout links + notifications if a purchase has many failed attempts using diff cards (you can do this for free through Stripe's API). I refund suspected fraudulent transactions religiously without question as the $20 dispute fee is crippling, and have systems that will auto-generate and submit evidence to banks whenever I receive a dispute. I wish Stripe would do more to help!
