You guys confused me because I couldn't see any emojis in any of your names. Until I clicked on @SgtSilverLining 's name and then the link to view the profile in the original instance. Turns out kbin doesn't have the concept of a display name, only usernames.
Looks like either you have a capital letter in your username and what I see is your username, or you don't have an emoji in your display name, or kbin strips emojis from usernames.
Edit: It appears kbin shows people's usernames, not their display names. That said, you still seem to have a capital letter in your username.
