I think the only danger on submitting our kyc is that our identity would be rob by scammers and use it for their own activities on fraud works.
Indeed. And what you said basically already stated by OP and others above. Well, that's why we must be careful and never share private data like our identities. You should ever hear that our identities can be traded on the black market. It is a warning, thinking about the risks before submitting private data to any project teams.
