From what I am seeing through my analysis of 'big' channels or people with large or loyal followings one word that may describe how they created that bond is 'honesty', being open with their subscribers, draw my life, talking about being bullied etc.
So to hide something for me already shows you are not being fully transparent.
Obviously theres nothing wrong with it. People may have their reasons, but with that in mind and the other responses it seems people look at it in a bit of a sketchy way.
