I was given a gift card by a random user going around the name of 'giftlind' I opened it up, and then I saw it was some TOS to grant permission to take money from my account, as soon as I saw, I closed it. I didn't click deny, or grant permission. I just deleted the object. I feel really scared, can someone help? This is exactly what I experienced. https://community.secondlife.com/t5/Abuse-and-Griefing/I-received-a-card-from-a-gift-avi-registered-today-that-when/qaq-p/2890525
