I feel you OP, The team that conduct the bounty campaign were good at first and very accommodating on every bounty hunter joining on their bounty chat. Afterwards in the middle or in the late part of the campaign they start to become rude and since you are already working few weeks and months with them then you will just behave so that you will not be remove in the campaign and you can get the rewards. Aside from that rewards are not readily given as promise.
Yes that's true especially if you have a good ranking in the signature campaign, this is the reason I only choose good bounty manager, to work and had a good record of addressing issues that affect the bounty hunters,like not getting their stakes for a week and explaining to each one of them
