Why the hell should he? He said he was ready to roll and that's all he needs to do until the other personage supplies more details. I wouldn't bother to personally satisfy the feverish desires of every reader here either.
Unsurprisingly this sounds like Roger playing the victim to me.
While I think it is weird that Loaded doesn't respond anymore, Roger does not win an award for communication either. If he really is so interested about the crowd's opinion, he could have done so many things to show that he is for real.
Communicate, lay out the rules of the exchange for open discussion, sign a wallet and his intentions, take up bets from other people who also have shown an interest.
Instead he didn't do anything, just saying how busy he is and waiting it out to buy time.
He doesn't have to do anything, those were examples of the part you left out.
He is the one complaining everywhere that people are drawing the conclusion that he has chickened out. Then do something about it I would say.
