Recently I found out that SOMEONE subscribed to 900 YouTube channels on my personal account. I wont say who :)
Anyway, with a little help from my local LLM I came across this script.
Very easy to deploy. Go to Your YT subscriptions page here:
https://www.youtube.com/feed/channels
Then F12 or right-click “inspect” to bring up dev tools inside Chrome.
Go to the “console” tab. You may have to enter:
allow paste.
After that, paste this: (and hit enter)
Copy to Clipboard
It will unsubscribe about 1 channel every few seconds.
Keep the console open and do something else.
Enjoy!
