Such channel is one named Enderman and his second channel Andrew that got terminated because supposedly one of his channels or both were linked to another a channel that was terminated due to multiple copyright issues which he surely wouldn't have known. First his secondary channel then his primary channel, soon after he posted about his secondary channel's troubles on his primary channel. Supposedly there was an AdSense account or something that were connected to that. After a while his channels and other affected ones were restored. Still, this is a disgrace and broken AI must be fixed. As long as channels are getting falsely flagged and terminated with false strikes on YouTube this is still an issue. The AI on on YouTube is running out of control and might also be broken. Only by making enough of noise such issues could be fixes, otherwise th future is bleak. Also it appeared that appeal system on YouTube would be broken, the channel would still stay terminated after the owner appealed the termination and the "human" reviewed that, only enough noise on social media would fix that.

As it's shown here, YouTube must do something about false terminations like above, reduce usage of AI tools and fix other related bugs.

Edit: reworded, fixed mistakes and added some missing information.

Edit2: Added more information as the mentioned channels got reinstated, this is a great success.
