Why even bother with registering emoji domains? Just allow people to register bob.<emoji>@mailoji.com. TikTok users probably wouldn't care where the emoji was in the email address. Most non technical people don't even understand email addresses (you work here too? is the most common question I get when I tell people my email is <theircompanyname>@mydomain.com). Only internet nerds really care that the emoji is in the domain name.
