That's a scam, totally preventable though. You can always TOFTT anonymously by getting a prepaid phone, prepaid Mastercard or Visa, a throwaway Google, Outlook, or Yahoo email that you can use for spam and site signups. When signing up for websites, I always use these alias/additional info instead of my personal details. There are sites that have free trial, you don't get charged at all, they just need the prepaid Mastercard/Visa on file if you subscribe.
OP, my suggestion is to review and search for these type of ads, if you've got hits or some positive feedback, then you can partake if you want to, if there are no positive feedback or reviews, stick to the regular recommended ones. You can search for pay per play with a cost or location preference (example, around $300/Vancouver area) - Your previous thread here:
