im pretty sure its a thing but the person that got donated to can block it or something its really forgety
i remember some dudes donated like 10 grand to some streamers as a joke and tried to chargeback afterwards but got blocked because the streamers where like "fuk u that literally wasnt a joke"
i think the point of chargebacks is that if you and lets say an online store agree that you didnt make that charge you can chargeback, but i think one of the parties can dispute it and it stops it
