I'm trying to hire a freelancer for a project. I've signed up in fiverr, freelancer and upwork. They all ask for my ID and I just don't want to share it, what is the necessity for that? Really, I want to understand why they ask for this type of documentation, please let me know if you know the reason.

Anyways, I wanted to know if you knew any alternative that doesn't require KYC

Thanks in advance!
