PayPal is a payment aggregator, meaning it doesn't specialize in high-risk payments. PayPal may suspend your account if you operate in a high-risk industry, receive too many chargebacks, or break any element in its user agreement.For this reason, if you want to access high-risk payments on a Shopify account, it's better to work with a high-risk merchant account provider instead of opting for PayPal as your high-risk payment solution.
