It's right. KYC is important for some reasons:
1. To reduce the spammers or scammers
2. To know exactly whether the participants or investors are real and allowed to join the ICO. Because some countries prohibit their citizen to join an ICO crypto.
3. It is KYC (Know Your Customer). This is important for the developer and the team to know who their customers.
4. It is also sometimes as a bank requirement of the ICO
But, we must be careful in deciding to sign the KYC or not. Analyze whether the ICO is not a scam.
You confused KYC for investors and KYC for participants in bounty ICO campaigns. For investors, and large ones, the KYC check is carried out in order to prevent the laundering of dirty money and combat the financing of terrorism. For any other purpose, a KYC check shall not be carried out. Therefore, in relation to bounty hunters, it is simply illegal.
By the way, bounty hunters cannot be considered ICO clients, since they do not invest their money in these projects.
