It's a question you have to ask now.  Does this ICO require participants to KYC now or in the future?

I have started a few bounties and after a few weeks participation they announce there will be a KYC.  It's really disappointing when this happens and there is no recourse.  What can you do?  You have just helped promote a ICO and without warning they add this big or even insurmountable hurdle if you are from a blacklisted country.  If you ask them they will say, "well we did stipulate we can change the rules whenever we want.  By participating you tacitly agreed to are terms."
