I do not think, this Scammer of a guy is still in this forum. He has scammed people and ran away. If that guy is in this forum, he has changed his identity. That was why you were advised to do transactions with a trusted person. Now that he has ran away where will go and see him to collect you moneys. A community of more than 5 millions people there must be an arm robbers, Scammers so it your duty to sort out yourself from them.
And from the OP thread, this case was since 2013. This is a long period of time. At that time I have not even dream of Bitcointalk in my life. One thing you have to think of is that, is the Scammer still existing I'm this world? And before, you did the transaction with him. Did you ask him where he comes from? Because you can't look for someone on internet or social media and see the person. We pray that God should arrest him.
