IG similar profile pics

I was just looking at some motivational IG profiles (not much of them have original content) and I couldnt help but wonder if all of these profiles have the same owner. Due to the Crown in each profile-picture.

Whats your thoughts?

For those of you who have many accounts, do you mark them in some similar way to show that they are yours?
