@Barbie_kalai @admin All servers. Verification is a lie, even on Twitter, and especially on Mastodon.

It is true there is no Twitter style verification on Mastodon. However, you can link to another website with which you have edit rights. If you create a mutual rel="me" link from Mastodon Preferences to that other website, you will get a green tick on your profile page, like this:

It doesn't prove anything about you other than you have access to a Mastodon account, and also have access to the other website, but that does have value.

Your instance needs to have the wanted emoji. I note you have 
for your display name. You have it capitalised, try all lower case.
