BitRewards bounty is now called one of the coolest and most interesting in the crypto community. I am also going to take part in it, but I would like to clarify a few points... Why are there restrictions on obtaining tokens by citizens of some states? Does this mean, that I can't advise these citizens to participate? Don't I break the rules in that case?
You do not violate, but the citizens of the United States of America and all territories under the sovereignty of the United States, China, Singapore are not allowed to participate. That's stringent prohibition! In an exceptional case, the company will reward them with the appropriate amount of ETH.
