I have all the requirements to be accredited, in fact I have much more than the request.
My channel have 20.000 subs, I post 2 videos per day and each of them exceeds 3 thousand views.
My channel has never even been warned by youtube, it has a credibility of 100%.
My videos are well taged even so, I continue to be denied. I dont know why, but I'm sure this is some mistake.
