Same with texts now. I posted a car for sale and within 24 hours, I had two texts from these numbers:
443-937-5353
904-289-5187
These people are almost identical in their texts saying they will send a cashier's check for the payment and when it clears, they will send a transport to pick up the car.
Ive never heard from them again even after calling their numbers and doing a reverse lookup to see who they are. My guess is they are cell numbers issued from a convenience store.
