One: This is a personal subdomain used for personal use only.
Second: I'm studying for my life in the UK test
And Lastly: I wanted something I could easily remember for the subdomain of the study material I'm using.
I am also under the impression it is 100% legal to do Emoji.MyDomain.com. You just can not use a emoji for the root domain. The root of a domain is is the text before the .com. This looks like THIS-TEXT-IS-ROOT-DOMAIN.com. As long as the THIS-TEXT-IS-ROOT-DOMAIN is not replaced with any emojis you are in the clear. Meaning EMOJI-HERE.THIS-TEXT-IS-ROOT-DOMAIN.com is perfectly legal under iCANN standards.
I acknowledged that typical domains do not use emojis in the domain name and the ones that do are 99% of the time flagged as a security risk. Rest assured this site is hosted by Google Sites. No Malware is on this site.Â
 Feel free to run this site through NordVPN's free link checker at https://nordvpn.com/link-checker/ and for the domain you put in the unicode url of my site written as xn--f77hja.Evan-Scanlon.comÂ
