Just FYI, when you block a payment instead of just emailing us and asking us to discontinue it, this results in a $25 chargeback fee for freeCodeCamp. Not only does this wipe out your $5 donation, but it wipes out several other people’s donations as well.
Please don’t block the charge at the bank level - just email us and we can discontinue it. I usually respond within a few days, and even if your card is charged after you email us asking for cancellation, I can refund that charge in Stripe.
