Misskey.io is operated as a service for Japan, but recently Japan number of user registrations from overseas has increased rapidly, and moderation has not been able to keep up. At the same time, it has become difficult to provide sufficient support, so at this time we are restricting the registration of new users from overseas. We will inform you again when we are expected to resume, so please wait for a while. Thank you for your understanding and cooperation. Related Entities registration
That is such a suspicious premise.
