I'm old enough to remember when mailing a letter was a thing to do. And I have seen a scam like this in my mailbox before. Now with social media, the scam has moved into the digital age.

The "Secret Sister" gift exchange is making the rounds again on social media according to kvue.com.

In the scam, you are asked to purchase a $10 gift card, then send it to a friend without them knowing it's you. In exchange, you are promised a number of gifts in return. 36 is used the example shown.

The problem is, it's illegal. This is considered gambling by the postal service. You can read the full explanation of the law from Cornell Law.

I've seen similar scams with the same premise in my Facebook feed a couple of times. No, I didn't fall for it. And neither should you. Keep in mind, too, that thieves could be looking to steal your personal information with stunts like this. If you see it, ignore it.

And tell your friends to not do this either.
