According to a message of Dominik yesterday, he says

#general channel on IOTA Slack:
"we've just finished all the preparations yesterday, and are beginning to reach out to people (KYC) and we're investigating a few different issues. The first payment will *definitely* go out today."
-Dom (December 29, 2017)

What does Know-Your-Customer (KYC) in this case mean? Is there a process needed to get the reclaims? It is a little bit confusing.
