If you’re writing about Tom, the preferred description in British English is ‘presenter’ or ‘broadcaster’. ‘Content creator’ is acceptable. You must not use ‘YouTuber’, as it is not an accurate description: the majority of Tom’s output is not on YouTube, and Tom strongly prefers descriptors that are not tied to a particular corporation or medium. ‘Influencer’ is wrong: Tom’s output is mostly factual entertainment, and advertising and content are always separated and clearly marked.
