Thing is, if she tried to return after a year fof absolutely no content she wouldn't be able to. She'd have lost any influence she still has. Constancy is the name of the game with influencers, which is also why she's been stagnant for so long. She's not Adele or anyone providing real value/talent.
She could have taken a proper couple months off, or more, if she had prepared videos and staggered their release and hadn't separated herself so much from Zoella. Something to keep her name in peoples', and companies', radars. But that's why influencers can't take time off. It's not that they can't afford money wise, it's that if they want to keep the gravy train going, then they need to be constant.
She's a tit business woman who only made it as big as she did because she was cute in a boring and safe way and it was the right time, that's the truth.
