Post a pool table to Craig's list, and you will quickly get texts from people who are trying to pull some sort of scam. This number is one of them. If you engage with them they will ask if the table is available, then offer to pay via PayPal sight-unseen. They'll ask for your credentials to pay. Then they will ask you to send money for shipping. Needless to say, you will not get paid and your money "for shipping" is gone.
