Greasy Fork

Great script! I wonder if you could extend this to Inoreader: I use that aggregator to organize YT channels and basically watch only from there, but Inoreader is content-agnostic, any new video of a subscribed channel is indexed unless filtered by user from hashtags/words. But Shorts cannot be filtered because 99% don't have the tag #short. In the past few months my stream has become crowded with that shit.

I done this script after I simply tried.
But there may be a few things to note about this script:
1. This is not a good practice because it may makes a lot of cross-origin requests.
2. Due to the cross-origin request involved, the shorts will not be hidden in time.
