JaneDoe, am I right in thinking that you contacted "David Brooks" and asked him about some of the points that were raised here, and that in response to these points he then followed up by sending the IRS forms that we had pointed out are needed for legitimate employers?
As a general rule, we recommend against confronting scammers with the points that were raised here. When a victim points out the problems with their scams, the scammers can learn from the information and improve their scams the next time. For example, if you tell a scammer you know something is wrong because he sent you the wrong form, he might take that information and send the right form to the next victim, making his scam harder to detect.
Once you know you are dealing with a scammer who has your real life information, the best thing to do is to cut off all contact with the scammer and file the appropriate reports with the authorities.
