"Honest" a big word lol.
Youtuber is not here to tell you what is true or what is real , they are here because they wanted to earn popularity and followers/viewers .
so what does that mean?
they will do everything just for you to believe in them and that is far from reality of life so never ask for whom we trust but instead whom we watch .
But, there must be an honest youtuber because they know that they can earn more subscribers and viewers if they are true to themselves rather than if they will lie. Those who lie and misleads can still a get a viewer or maybe subscribers but that will only be temporary as their viewers will find out the truth soon.
There are youtubers like that, where they can do anything what you want but they are only doing it for a challenge or they are being challenge by their viewers. That is a legal way to get subs and views. Some of us not only watch a video but we also trust the youtuber behind it. This is what the op wants to know. There is nothing wrong with that.
