From the very start ask your bounty manager if the rules are already firm and final.
But the sad thing is before you are going to ask them, you'll see one rule that allowed them to change any rule as they wish.
There is no constant in bounty rules. They can always reject, remove and change the rules as well as the hunters. We are not a regular worker and they are also have rights to do that. Therefore, even we ask them nor we tell them our opinions, we can't predict what their next thing to do. A lot of bounties I have worked for several months then end up of changing rules. So, I agree with you.
If we want ti avoid KYC, don't join campaigns.
