Hello. The status API endpoint returns undelegated/inactive status for single letter .ru domains. But I believe the registry does not allow domains to be registered that are 2 characters or less. Example:

Request:
https://domainr.p.mashape.com/v2/status?mashape-key=XXX&domain=o.ru


Response:
{
  "status": [
    {
      "domain": "o.ru",
      "zone": "ru",
      "status": "undelegated inactive",
      "summary": "inactive"
    }
  ]
}

Would expect the status/summary to be disallowed or unregisterable instead. Thanks.
