Don't comply and don't join bounty with KYC! Simple as that.
I have been telling this all a long, ignore bounties with KYC. There is another problem, they say KYC is not necessary for bounty hunters and after bounty and ICO they say bounty hunters have to give KYC. It happened to me several times.
I still join the required bounty KYC in case of potential projects. Because maybe that project will bring me a big amount of money in just a few months
