To participate in an ICO, maybe KYC will be needed as some countries don't allow their people to engage in such trade but for bounty participants it is sad to note that team are doing this maybe because they want to catch cheaters and not to know where their token will go to.
KYC verification is aimed at not restricting the use of multiple accounts in ICO signature campaigns. For ICO teams, it doesnt matter how many accounts you use, just to write high-quality messages with their advertising for the ICO project. The requirement to have one account is more the rules of this forum, which in their conditions are forced to duplicate the joining of the ICO team.
The KYC check is used to prevent the possibility of laundering dirty money and cannot be used against bounty hunters.
Therefore, if a KYC check is carried out at the end of the ICO, then it is only with a fraudulent purpose not to pay the earned tokens to the bounty hunters.
