I'd say Creative channels where it takes a while to make a video, you put your own blood and sweat into a production and because it's not cutting edge hype but your own talent, your own story, you are usually overlooked and get your feelings hurt.
Other than that... I'd say Channels with no goals, no aspect of what type of videos they want to make and just try to do them all till they get it right. I've been kinda there.
