Actually Zillow, what the scammers do is ask you a plain question that they know you will give an answer to, like 'is your name Suchandsuch?' If they have your name and contact information from some other identity-stolen source, you would say 'yes'. But what they have actually setup behind the scenes is a pre-recording that might actually be 'Do you give permission to accept this call ?' Or, worse, if they have even more identity-stolen information of yours, 'Do you accept this charge?' Your initial innocent 'yes' will be recorded. Then one day you will have a bill or credit card charge for hundreds or thousands of dollars, and if you contest it, they will have your recorded 'proof' that you did indeed confirm the charge.My example might be simplistic, as the actual setup is more complicated, but you get the general idea that the questions you are being asked are different from what they setup their recordings to be. There is a public service warning somewhere regarding this very scam, but I can't cite the source at the moment. You are warned not to answer any questions from a source you are not familiar with, or if you are suspicious of the source. Verify their information first before answering any questions, or simply hangup. If they identify themselves as a company you do business with, it's even trickier. If I locate the public service warning, I will return to this site an post.
