It's a new scam that tries to use your phone number to scam others. If you post your phone number in any public forum, you could be at risk.
An ABC11 viewer discovered the scam in a quest to get rid of baby equipment that he no longer needed. He posted an ad on Craigslist trying to sell a baby swing. It didn't take long for the seller to get requests to buy this swing.
In the first text, the buyer agreed to pay cash, but to make sure the post is not fake, the buyer texted he wanted to send a Google code to the phone number listed on the ad.
