It's a little unfortunate to read this, but it's weird, although I don't use patreon for stories that deal with the same concept as this fic and I never got a warning. Or at least the authors never said anything about receiving one.
hey how about this, you take the vtubers concept from this and make a fanfic out of it cause i never seen other that try this type of concept of creating a vtubers agency but they are real person. as far as I know I don't see this concept a lot
