Anyone who wants to give it a first time try or a try should first ask on proofs regarding scam incident and check if the scam really occurred or not.

You should know that starting your investigation on no strong basis might lead to doxxing of an innocent.

At the same time I request OP to post in Scam Accusations >>Investigation section (if scammed by someone conducting business inside bitcointalk) or if not then mention about the proofs of the scam incident in thread.
