Honestly I just think if Molly's life had anything going on it would be doing better. People like Eve because she has stuff going on outside of influencing. Molly's entire life revolves around being an influencer, she has no hobbies and interests that aren't online, and it shows.I think on the whole people are boring of influencers who's only job is influencing. Unless you can be "aspirational" and buy loads of designer gear, having an amazing house to show off etc. People are far less interested in influencers in the middle - those who earn enough (or who are supported by their parents) to not get a real job, but don't earn enough to have much to show off.
I actually think if Molly had a real job her channel would be doing much better
