In 2022, their TLS certificates were off -- a subdomain used by a backend redirect process was no longer valid, so I contacted "ML" and they were unresponsive. I managed to get my domains to a new register by ignoring some TLS warnings and transferring them. As of July of 2022, I have not heard from "ML" and I assume that he passed away. I don't know their identity or what became of them. All I know is that their name is/was Mark.
