Yes, I am sure he was originally smart1985, who later changed his name to mybitcointrade.com. I remember some of his posts from 2011/2012.
Wasn't he also the guy who sent bulanula 25 BTC instead of 2.5 BTC?
That's correct. He was orignally "smart1985", then changed his name to "Smart-Mybitcointrade.com" I believe. He was called just "mybitcointrade.com" at some point.
