I contacted the real shasan on his post and on his real Telegram to verify first (https://bitcointalk.org/index.php?topic=5475140.msg65029321#msg65029321), I knew it was a scam but I played along to get as much as information I could.
The funny part is that he said I was the scammer before insulting me and deleting the whole group chat, he lost his patience as I was not falling for the scam 

So far I can see we have few of his wallets addresses, they all link to MEXC, we need to contact someone there that can freeze the funds.
Also we have the voice record, maybe it can help to identify him

Done and I updated in the main post
