If a stranger on the internet promises you a Christmas gift for a $10 buy-in and some personal information, it probably isn't legit, the Better Business Bureau warns. Not only will you be conned out of a gift, but you might have accidentally joined an illegal pyramid scheme.
"Secret Sister," an internet-wide gift exchange that tasks users with fulfilling each others' Christmas lists, is an illegal scam that could put personal information at risk, the consumer watchdog nonprofit said.
