He's posting an Imac on craigslist. Don't know if this is valid or not but that phone number is on this craigslist ad.

I got a text from this number trying to sell me what seemed like stolen Apple products.  I told the guy to screw off and then he sent violent threatening texts.  Anyone had this problem?
