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, tattoos, location data, and recognisable details can identify you even when your face is hidden.
Decide in advance what you will never show or share, and treat that line as fixed. Strip location metadata, be careful with anything that ties your persona to your legal identity, and assume anything you post could travel. This separation is also the heart of your persona and your long-term reputation.
