unofficialKYC is a platform for users to link their accounts on many online
services to a single charitable donation, without having to share their
disclose their real life identity or shared identity between those services. In
doing this, UFKYC provides a way for companies to penalize the creation of many
different accounts, without requiring genuinely new users to pay money they
haven't already provided for another service, and without having to require
identifying information like passports or IDs.
