Guys wake up, this is shine from sythe.
To verify him, simply use his livechat noted on his profile here or sythe -> https://www.sythe.org/threads/3k-vouchesshine-buy-sell-exchange-cryptoswechat-bcc-eth-alipay/
If his account were hacked here, his sythe account would be banned also but i don't think that's the case.
He's Chinese and using exchanges wallets since forever.
Im not defending him, im just telling the truth.
He won't be able to send any signed message for sure because of the wallets he use from exchanges.
There is many other ways to verify him (skype/email/whatsapp/livechat/wechat/icq)
