I think it's better you create a fresh scam accusation topic and include a little more details, such as the TX ID showing that you made payment to him. You claim that the scammer deleted all the chat history, but in the link you shared, I see some screenshots of chats. Why don't you share those chats too?

I am sorry, I can not tag the user unless you make a proper scam accusation and add more proof showing that you transacted with him and ended up getting scammed.
