The latest trend among YouTube’s hottest stars: feeling burned-out by the whole experience.

Having achieved success, some top influencers are deciding to disconnect from the video-sharing platform, worn down by what some say are the demands of YouTube’s algorithm for fresh content to promote.

Last week, controversial YouTube superstar PewDiePie, who was the first individual creator to hit 100 million subscribers, said in a video that he was taking a break—“I’m feeling very tired”—as did the comedy duo Ethan and Grayson Dolan in October. In their video, posted on YouTube, the Dolan twins said that after five years of posting to the platform every Tuesday, they needed to stop posting every week to preserve their mental health.

“We have a job where you can’t just take off because there’s the fear of becoming irrelevant,” Grayson Dolan said. “I can’t even go home to see my mom.”

The New Jersey natives started posting to YouTube when they were 14 as a passion project, and then moved to Los Angeles when it took off. Now 20 years old, they have accumulated more than 10 million subscribers.
