I had a conversation with him just now as well. Very scammy demeanor and poor English skills.
Me: Hi redball, I have 3k PXC to sell. You can check my rep and tell me if you want to trade. thanks
Him: ok...I take the 3kPXC for 16LTC. ok...its up to you if you like to trade in one ore more batch. my PXC wallet: PfZrtg6zz2QddLkVb51EnTTcmmDknc8a7i I will send you the LTC after I received the PXC. What is your LTC wallet?
Me: Sorry, not sending first to you. I have more rep and post count at the moment. If you're willing to send first and trust that I usually reply instantaneously, give me a reply
Him: its ok...I do the trade with other peoples .)
I would give him a negative trust rating then report his ass to the scammer accusations subforum
