Keep your creator identity separate from your personal one at every layer: a distinct persona name, a separate email, and payment details that do not expose your private life. Before you post anything, think about what it reveals — backgrounds, reflections, window views, mail, tattoos, and location data can identify you even when your face is hidden.
Strip location metadata from files, decide in advance what you will never show, and treat that line as fixed. Building a strong public persona and keeping your legal identity private are two halves of the same job, and they reinforce each other when done deliberately.
