If a channel has no subscribers, it can be deleted without issues. This process is irreversible, and the channel cannot be restored once deleted.
Here are the steps to delete a channel
Go to the channel page you want to delete.
Click the pencil icon in the upper right corner of the channel card.
On the editing page, select "Channel Details" in the top right corner.
Click the "Delete Channel" button on the bottom of the page.
Note: If the Free Channels contains paid posts, users who have purchased those posts will still have access to them in their library. The posts will be marked as "Not Relevant", but users who bought them can still view them. All free posts and other information will be permanently deleted, and the channel will be removed entirely.
Note: The owner can only delete a Paid Channel if it has no subscribers. To do this, the owner must stop charging current subscribers and prevent new users from joining via the channel settings. Once there are no subscribers left, the channel can be deleted. Similar to free channels, any purchased paid posts will remain accessible in users' libraries and marked as "Not Relevant."
