If you configure your Fraud Management Filters to simply "Flag" a payment, E-junkie will treat it as a normal payment.
If you configure your Fraud Management Filters to "Hold" a payment, E-junkie will treat it as a "Pending" payment and depending on your setting in E-junkie seller admin > Payment preferences, we will process it or not immediately. If you preference is set to default (to NOT process pending payments like normal payments), then we'll only process the payment once you login to PayPal and approve the payment.
If you configure your Fraud Management Filters to "Deny" a payment, E-junkie does not get to know about it and thus has nothing to process.
