YouTube mandatorily keeps a history of all the comments you’ve left under your account, along with other activity. This means that you can view them at any time.
The service also allows you to delete previously left comments if you suddenly change your mind or decide to clean up your virtual presence.
It is enough to simply pass authorization and go to a special section of the settings, which contains all the comments ever left on YouTube. To do this:
Open the YouTube site and make sure you are authorized in this service.
Click on the icon with three lines in the top left corner.
Click on the “History” item in the vertical menu list.
Now on the right side of the vertical list, tap on “Comments”.
This will open the “Your YouTube Comments” action management section with a list of videos you’ve watched and your feedback on them.
