First of all, If I wanted to cheat I would have used a different name and totally different bitcointalk account for that. Why would a cheater use his own bitcointalk account in order to cheat knowing the fact that he is gonna get caught anyway. That doesn't make any sense at all.
I actually think it's okay for a bounty manager to participate in his own campaign as long as it's transparent and clear. .. However, I am wondering why didn't you add your username in the spreadsheet then? What's the need of adding a random username like (bluhori)
Because This is his first bounty campaign. I encouraged him to do it just using my BCT link.
