KYC verification is not performed to eliminate individuals who have multiple accounts in one ICO signature campaign. In principle, the ICO team in general whether you are using one or more accounts at all. These are forum rules, not theirs. It is only important for the team that you send useful messages promoting their ICO project.
The KYC check is carried out to prevent investors from laundering dirty money. Therefore, only investors should pass this test. Neither the United States, nor China, nor other countries require ICO teams to require KYC to be tested by participants of the ICO generosity campaign. This is purely an excess of its authority by the ICO team, because in this case our right to confidentiality is violated. In my country there is a law that clearly states that only public authorities have the right to breach of confidentiality in cases provided by law.
