Registrar is 1API.NET which uses Verisign.
DNS is currently configured to cloudflare (maybe as a result of this fubar scenario?). blah.itch.io would be pointed in DNS not from the TLD registrar in this scenario.
Contacting itch.io directly would be the first step long before going the registrar route as they obviously manage DNS on their end and not the registrar end.
