Most accounts carry three names. The display name is decoration and freely editable. The @handle is unique on the platform but usually changeable. Underneath sits a permanent ID the platform never changes — the account's true identity.
Why the layers exist
Handles make accounts human-findable; IDs make them machine-stable. When a creator rebrands, the handle changes and every ID-based system keeps working — links, APIs, and trackers included.
Why trackers key on IDs
A follower counter that stored handles would break on every rename. Our YouTube counter resolves whatever you paste — handle, URL, name — to the permanent channel ID, so a milestone link keeps working forever. The full YouTube naming story is in handles vs channel IDs.
