Same scenario as everyone else, although he has been contacting me through two different numbers. the 646 numbers and a 707 number. I caught on right away as I was curious why someone would send me money so that I could pay for the moving service. I played with him for a few days and then once I received the check, I wrote on the check "you've been scammed" and texted it back to him. Haven't heard from him since.
Same thing happened to me. Trying to sell my drums on CL. Luckily for me, I read up on his contact info! Always google the phone # and email address, there are plenty of good peeps out there trying to look out for one another.
He's still doing the same thing. He is using this phone # also -- 1-312-298-9286.
As soon as he went into his spiel about me cashing his check and wiring money to his movers, I emailed him that I wouldn't do that. Now, I wish I had agreed to it -- with no intention of following through. It would have felt good to hand the check to the police.
I didn't get hurt, but I learned a lesson about checking out phone numbers.
