YouTube’s system for suppressing low-quality AI content mistakenly targeted Kurzgesagt, causing the animation channel to suffer its worst-performing upload since 2013.
The educational YouTube channel, which has more than 25 million subscribers, said it first noticed unusual fluctuations in its views before its video about superpredators performed “extremely” poorly.
Kurzgesagt found the drop especially suspicious because nearly every major metric was above average. More viewers clicked the video, watched for longer and responded positively, yet YouTube seemingly stopped recommending it.

After contacting YouTube, the channel said staff quickly confirmed something had gone wrong.
“It turned out that YouTube’s automatic AI detection tools wrongly think that our very much human-made videos are AI Slop,” Kurzgesagt explained.
YouTube’s AI Detection Kicked Us in the Face
Every creator’s worst nightmare just happened to us: The YouTube algorithm actually blocked us. It started slowly at first. Some videos started showing strange view fluctuations. Our second to last video did very badly, but this just… pic.twitter.com/HP6vIQ3vGc

The channel said the false flag began to “choke” its reach. YouTube reportedly helped address the problem, although Kurzgesagt said it could only hope the bug had been fixed.
Kurzgesagt has since taken the superpredator video offline and plans to upload an updated version within a few weeks.

YouTube creators fear AI slop false positives
In a video covering the incident, creator analytics company vidIQ argued the undisclosed restriction amounted to an apparent shadow ban.
“If YouTube detects AI content as slop, which we’ve already well established Kurzgesagt isn’t, it will choke the channel,” vidIQ said. “AI slop equals shadow ban.”
Furthermore, due to Kurzgesagt’s size, they were able to quickly get in touch with YouTube and resolve the problem, a luxury not afforded to smaller channels.

“As one 5M subscriber creator experiencing a similar decline put it: a channel that big can find out and correct this, but not everyone can,” vidIQ noted.
The open question is access. Kurzgesagt had people to call.

In the comments, dozens of other creators expressed fear that they too had been targeted by YouTube’s AI detector and had their reach “completely dead.”
The company also highlighted a Google Research paper detailing a detection system deployed on an unnamed major video platform. The system reportedly terminated 50,000 clusters containing 130,000 synthetic spam channels over six months.

The paper does not identify YouTube as the platform. However, vidIQ believes the system was deployed there because the researchers are Google employees. It also reported an overturn rate below 1%, which could still represent hundreds of false positives at that scale.
YouTube CEO Neal Mohan previously vowed to combat low-quality AI content after a report found 21% of videos recommended to new users were AI slop.
The platform later removed or emptied major AI channels and clarified that repetitive or “unsatisfying or off-putting” videos could be demonetized.
