Can you completely remove or delete this profile from your site?
Go to: Preferences 
Account then at the bottom of the page you’ll see “Delete My Account”
I did what you said but I couldn’t find it, can you send me a screenshot?
Not possible, only new accounts can be deleted by users

What account are you referring to? The one in this forum? Your Clash Royale account? Your esports profile in RoyaleAPI?
I’m talking about my account in this forum
Ok, then as I already said, it’s not possible, only new accounts can be deleted by users
