Payment processors have a way to block prepaid cards, and I wouldn't be surprised if many organizations used these as a blunt instrument to prevent fraud. A political organization can probably even decide to treat those transactions as though they were anonymous cash donations. Though, I'm thinking of the US, so this may be different in Canada or elsewhere. See, e.g., https://support.stripe.com/questions/find-the-type-of-card-a-customer-is-using https://support.stripe.com/questions/find-the-type-of-card-a... > The funding parameter of the card object exposes whether the card is a credit, debit, or prepaid card. A card may be unknown if Stripe was unable to determine its funding type.
