Thats why better to join bounties by third party managers and those who are into bounty management for quite a time now. You might not know if the bounty manager is part of a team or not. If he is somehow related then he might take some decisions favoring his team's side.
Also they should release name of the bounty manager. They owe a detailed explanation regarding your case.
The bounty was initially handled by a third party Bounty Manager, but after the bounty program, they said he was unfair in the distribution of the tokens and so they hired an "Independent and Professional Auditor who is a respected member of Bitcointalk Forum".. At least that is what they told us, a bounty that didn't intially require KYC, they added the KYC and I passed with flying colours, in other to make it impossible to receive tokens, they accused a large number of bounty participants to be account farmers.
