Just so the honest folks here are aware, I have received a couple of emails ironically to myself from myself that actually came from https://uk-c.co/ which points to Mail-in-a-box. This would help explain why many of you are being blocked as spam. The format of these emails is firstname.lastname@example.org.
Might I suggest that you file a complaint with the registry?

Thanks. I followed through but after a longish buck-passing trail it ended up in Russia where everybody said its not their responsibility to act on anything from “third parties”. I’ve reported it to the various anti-spamming groups but whilst registration services are able to defer to their sub contractors, who can do what they like, then the system will remain open to abuse.
