although I agreed with KYC should not be asked from the bounty participants, but bounty hunter no choice, how about you work for 2 month and finally need to pass KYC to receive reward, then no KYC=No Reward, so we must follow project dev any decison, even they don't paid to us, we also nothing can do, such as latest one is tokenpay
KYC is one of the hindrance why some bounty hunters cannot join the bounty campaigns because they have no supporting documents to verify their identity as some are still minors and wasn't able to get some identification cards. I have no problem with KYC myself but I think it should only be applicable to the investors of the ICO because the bounty participants are just promoters of the campaign but then if the team ask for the identity of the participant then we cannot do something about it as they are the one who will distribute the coins. You can have a choice of either not joining the campaign or submit the needed documents.
It could be a scam or a legit one. But now mostly when im talking about those legit bounty manager those who had an KYC is those one that is really successful one, they do that because they will filter those bounty hunters that has a multiple accounts on their campaign but we should be careful because they could use your identity to fool others
It's a good way of filtering those who has multiple accounts as we know there are many people who will attempt to cheat especially if it has large bounty amount so asking for documents would be the best way to filter it. Submitting your documents though may impose a risk that your identity will be use for something illegal but if it is for a reputable manager and good campaign then I would just submit what I am supposed to.
