Don’t fall for a holiday gift exchange called “Secret Sister” because it’s really a pyramid scheme. The Better Business Bureau says consumers should avoid what is really considered by law to be illegal gambling. The scam promises 36 gifts in exchange for one $10 gift.

The Better Business Bureau says consumers should ignore “Secret Sister” requests. You can also report them to Facebook by clicking on three little dots in the upper right-hand corner of the post.
