I know this is an old thread and I may be old fashioned, but "Youtuber" and "Social Media Influencer" shouldnt be career choices.
How about TV producer? Actor? Cameraman? Sound engineer? Editor? How many people have to be involved in producing entertainment to make it legitimate?
That said.... the girls (and guys I would assume...) who make a living sticking their ass out on Instagram....I think we have common ground there.
