I was quite surprised that I could easily find my Youtube account with public data like my playlists using my Gmail address. E.g., assume the address is
mrpoopie@gmail.com
Then accessing
https://www.youtube.com/user/mrpoopie
my profile shows up. Note that this works in incognito mode.
How do I completely disable this?
Note that I do not want to simply hide my playlists.
