After doing some research I found these types of videos were more fabricated than I anticipated. It is really sad they are using this to make money, recommending a service that by their own description is not that good. Using something, people in the real world do suffer, and tell everyone you have it, just to promote a sponsor. Bad move.
I noticed this trend as well. Many famous youtubers posting a video talking about being depressed and then pushing this service.
Now pushing a service for pay is no big deal on youtube, we all get it. Most videos have sponsored ads today.
But that fact that so many famous youtubers all made similar emotional videos and ALL shilled the same service is not an accident.
