Finally the suspicious campaign ended terribly after the bounty manager ran away with all the money but luckily the owner paying the participants from his own pockets again.
But the good news is Yahoo is going to continue their campaign most trusted manager of our forum!

That's why I was opened this thread. Without trusted escrow joined a campaign is not safe. Amount wasn't not small. I am not sure manager skip or they show excuse to scam people. If they pay participant that's good. If don't want to pay that means it's well planed skip.
Exactly, and thanks to you we have been calling it day one about escrowing the funds. Perhaps the owner wanted to pay those work hard to promote his website but he made a mistake of handling the bounty to someone who doesn't have a experience in the first place and unfortunately, has exited with the supposed money allotted for the campaign.
Btw , I am not sure yahoo going to manage their signature campaign. Can you give us reference ? Although yahoo going to manage but I believe he will consider about payment for existing participant. It will be better is be agree to manage their campaign. As well as I know he will not manage without escrow ( also he is an trusted escrow ). If manage by Yahoo , I will wish to join too☺
Here's what Yahoo said:
I am currently speaking with the team, users will be paid from old campaign before i'll take over and of course i will be holding funds when/if i take over
