Using slightly vulger wording in a github io page

I recently purchased a domain with a slightly vulger name, I was looking into hosting the home page using but I am wondering if the use of vulger words (like the f one used in the domain name) is allowed on the page, I looked through the “whats not allowed” section of the github docs but couldnt find a clear answer on this.

The main things I am concerned about using are the domain name which contains the phrase gofuckyourself and the wording of the website which also contains that phrase a couple times. If someone could confirm whether I am allowed to do this without risk of going against some ToS rule then that would be great!
