Well, he only gets commission if the users actually make a (monthly) profit... if it's a loss, he gets nothing. So, theoretically at least, it is in the bot creators best interests to make sure that the bot works and generates profits.

Also, just as an update, the bot has been quiet the last few days... no trading to speak of since the big loss (excluding the daily API bug workaround instatrades for 0.000000xx btc).
