To my understanding, KYC simply means "Know your customer". Investors(customers) who participate in ICO are made to go through KYC process before they are even allowed to purchase their tokens. On the other hand, Bounty hunters are just "part time workers" of the project and not customers.
I guess there could be more strict KYC procedure for workers(even if they are "part time") than for investors because people who advertise project are more responsible than people who invest money in it. If I am wrong in terms of law correct me please.But this doesn't mean I support KYC at all, just simple addition.
Even if they will be made to go through a KYC process, it should be before they start working and not after. Waiting for them to finish working for the project and refusing to pay them because they failed to pass KYC afterwards is a total cheat.
Imagine how may fake ICOs will launch bounty topics just to receive bounty hunter's id's. And there is no need to wait till bounty campaign end 
Wrong.And I really don't understand one thing - why KYC is even required. For governments? What does this mean?
