I assume the newbie account with the Cooper member who is the bounty manager is operated by someone who is used to doing this. This is just an assumption, there is no incriminating evidence yet. but from what the bounty manager does and the attitude of the bounty manager. clearly shows unprofessionalism.
There's nothing wrong with that, the forum allows you to create alt account as much as you want.
Obviously and bounty is very much a session and part of the forum but then, when you linger in this field (bounties) full of scams and worthless tokens, you’re often sure of what to expect.
More over, having a manager in a new account, I’ll live that one there.
Most times people work on a project, you as well be good to look up the manager of the project and that would by far serve some guarantee on fulfilling promises made to participants.
I can see that your manager @OP has been active through 28th November, you could as well @OP keep up talks with your manager, maybe he would update you on what the issue is and when you guys would get your reward.
