They do go mad. I met a gaming YouTuber that seemed like he was on the verge of snapping. He seemed so fake and disingenuous. Not that he was a bad guy. He was a very nice guy but talking to him seemed so artificial like he was being watched and always had to have a smile on his face. He didn’t come off as natural. But I guess if you do 6 hour streams playing video games every day, you habitually act like there’s a camera in your face all the time.
