That user have 1 post . In the forum even you more than him.
Also he deleted his post why would you trust a newbie ?
I don't want to be victim-blaming but where do you get the idea that it's ok to transact with newbies here, you are trading to a stranger that will just go off and he'll have nothing to lose, this is not the first I read members transacting with newbies and getting scammed I wonder when this will end that people should research or ask first before trading, even if it's a small or big amount it still disgusting to see newbies can scam here in Bitcointalk.
