Read the comments on the first page. KYC is not required for the Bounty Participants. But, they don't exclude the possibility in the future if someone will impose it to them.
To introduce or not KYC - this decision is taken exclusively by the company's management, and no one else.
Thank you guys for the question.
At the moment KYC is not necessary for bounty purpose
This is Bad answer. Will or will not have a KYC need to know in advance!
I will not participate in your Twitter and Facebook bounty companies until I find out an unambiguous answer to the question about KYC.
