I think bounty manager or the team should announce about KYC at beginning of their bounty, at general rule.
If they ask KYC at the end of bounty, I think we should rethink agian to share our national ID.
Because as long I joined bounty, many of projects which ask KYC at the end are scammers.
We must be careful, mate.
When bounty hunters are asked by a project team to perform KYC at the end of a bounty, it can be for any number of reasons:
• The team doesn't want to pay bounty hunters and uses KYC as an excuse, knowing that a large percentage of participants won't.
• The team believes that bots have been used to perform the various jobs.
• The team wants to use the official documents of the participants to sell them on the black market.
• The team may have legal problems if the data of the users who own tokens of their project are not known.
Those are usually the reasons most used by the teams, but they can also be for several of those reasons at the same time.
