Yeah, I don't want to be that person, but using anything of mine without my permission is not alright, regardless of whether I get charged or not. If it doesn't belong to you, don't touch it. That's like someone stealing your credit card, you realize it and cancel it before anyone can use it...the thief didn't take any money from you, you weren't charged, but it is still theft. You can argue it isn't the same because the process of getting a new card can be a pain, and the physical item taken was not returned, but either way it's theft to take possession of something without permission of the owner and the person IS using their card even though there technically isn't a charge. Also, I'm pretty sure Hulu or Netflix will charge a dollar or so to the card even during the trial that it will refund to you, just to make sure the card is valid and working.
tried that, my 30 day trial expired so i mAde another account with my mom's credit card and the day after i got a notification that my device was already used to create an account so they cancelled it, had to start paying netflix if i wanted to watch there
*this card has already been used for trial before*
