Decline problem? (Patreon)

I saw some of the Patron I followed having this post, copy pasting:

your patrons are having any trouble, here’s what they can do:

1. If their bank suspects that the Patreon payment is fraudulent, a patron can call up their bank to confirm the payment is theirs and genuine.
2. If their payment failed, they can follow these steps or switch to a different payment method.
3. If they are seeing an international processing fee, they can switch their pledge to a different bank that doesn’t charge for international payments.
4. They can reach out to the Patreon support team to get account specific help.
