Your bounty managers aren't only managing one bounty but most of them are managing more than 3 at the same time. And that's why they have to make a rule that will be easier for them to track down reports so if you didn't comply to what they are asking properly, you will be missed.. My take on this is when you are joining bounties, just simply follow their rules.
yuP we must follow carefully and never missed a single details,because sometimes this is what the damn managers waiting to take our stakes ,i have been once a victim whe i didnt put my ethereum address instead i put a telgram name,when the campaign ends and i double checked the details why i didnt recieve my stakees then i found out about the issue,and that manager didnt adviced me about the wrong address instead i have seen in the transactions that it was changed with a different erc20 wallet
