I searched for .rugby. One is the IRB (the main governing body of rugby basically, which is understandable).

But also one from "dot Rugby Limited" which if you look closer, is a likely brand new LLC purely created to bid on domains. They also applied for .soccer, and the emails are all "icanntas<number>@famousfourmedia.com", the number I assume corresponding to the number of applications. Rugby is at 23.

Their site basically says "we're going to buy tlds to make money off".
