I would like to thank you for mentioning the backnumber feature. I haven't used it before and will keep note of it in the future if I end up pulling a lot of videos from one creator like I did recently.
Also, if I can add my two cents, I also think that there's also an aspect of enjoyment in getting one's works past 'the system'. Personally, I derive some small enjoyment from seeing works like you'd mentioned, the kind that seem sfw but really aren't, on YT, a platform which actively does not allow such things.
