I saw this guy post this message in the Developments & Technical Discussion section -- it is now deleted but he posted it elsewhere:
I wonder if there's any BTC holder dumb enough in the world to fall for this.
why do you think badly of me? if the buyer will not found, then I will tell everyone this for free in this topic
I thought hes joker so I PM him and this is his response:
This is not how private keys are generated. Even if it was, hes not narrowing down significantly for brute force guess. My summation: this guy is a scammer.
What do you think?
I know hes already red tagged.
