Let's think about it. How is KYC stands for? I think everyone understands that this is knowing your customer. But bounty hunters are not exactly a customer, so what does bounty hunter have to do with this? No, and in general, I think it is against the law.
You raised this topic correctly. In the relationship between the ICO team and bounty hunters, the clients are the ICO team, that is, the client always pays for the services rendered. Therefore, if you use the KYC system, then the ICO team must pass it in front of the bounty hunters, and not vice versa. This is precisely to the fact that only investors must pass such a test. If anyone wants to eliminate the use of multiple accounts by one person, let him come up with a way not to violate our privacy rights. And in general, the ICO team is in general whether you use one or several accounts all the same. For them, the main thing is that you send useful messages advertising their ICO project.
