a well curated (pruned of anything you don't like) watch history is essential to getting a good youtube experience. it's pretty much the only signal that drives recommendations.
… why do I need to delete something, that’s frustrating :( I don’t want to need to log out and turn off my ad blockers to watch something weird or abnormal on YouTube… I pay for premium for a reason :(
there's a pause watch history button on the history page
or incognito mode
or just open it in an incognito window
