The domain has been registered on September, the 1th of 2018. They started their first advertisement on October, the 29th of 2018 and came online on bitcointalk on November the 12th of 2018, one week before the new director and shareholder have been registered at ACRA, the authority in Singapore. Anyway, the old logins don't work. Probably the reason that they didn't publish the new platform on the old twitter account.
