Every holiday season, the Better Business Bureau issues a warning for one particular scam which pops up on Facebook known as the “Secret Sister Gift Exchange,” but is in fact a pyramid scheme.

The scam has been floating around Facebook and Reddit since October of 2015, according to Snopes.

“Purchasing one gift and receiving several in return may sound like a harmless way to give and receive presents, but this seasonal scam is a pyramid scheme, which is illegal,” the Better Business Bureau writes.

The BBB advises that you altogether ignore any kind of snail mail or social media gift exchange.
