Online Content Creator

This character is an online content creator.

An online content creator is someone who mainly creates material to be consumed by people on the internet. It could be a video, an edited image, a website, app, or anything in between. It might be monetized in order to make a living, or simply done as a hobby. Examples of online content creator are Bloggers, online publishers, newsletter authors, podcasters, YouTubers, course creators, and video game streamers.

Note that the content in question should be created intentionally in order to be served to an audience, so anything for personal use shouldn't be counted, e.g. a personal Virtual Avatar used in a game. A person whose social media is never intended to be served as "content" should not be counted either, even when they have a lot of followers.
What's important is an audience, content, and intention.
