That's true, however whoever provided you with the card is responsible for ensuring you are not misusing it. I once had a trial with a company and added my Privacy.com card that would expire in a day. I've canceled that trial and forgot about it. Then some time later I had to use the same company, but I've totally forgotten that I had an account with them (I've also changed the email I use). Anyways, privacy.com suspended my account because using their cards to get trials over and over again is against their ToS.
