This is the right place to request a removal.
This domain isn’t actually on the policy lists anywhere! So in this case there’s nothing to be done from our side.
I checked our server-side logs and was able to see more context for this error:
400 :: urn:acme:error:malformed :: Error creating new cert :: policy forbids issuing for: \"explore the north\""
It looks like the policy error is actually for a domain you specified with some spaces in it, and we can’t issue for that domain because it isn’t a valid domain.
I would recommend you double check the way you’re invoking your ACME client.
Are you using Certbot? If you specify more information someone may be able to help you figure out where this misconfigured domain name is coming from.
Hope that helps!
