Your game is paid and I imagine that would complicate things. Also, if you removed content, you can always put it in again. If I were staff, I would refuse to remove the nsfw setting of that project. Oh, and your game description still hints at nsfw content. And people that downloaded it earlier, do still have a nsfw game.
You could have two versions of the game. Not change status of the existing game. Make the old project the project that people bought and maybe create a new project that is nsfw from the beginning.
Also, why is this paid and the files are named "demo"?
If you are talking about "fresh", I would assume that games get regularly removed from that list. Else it should be called Itch's favorites and not fresh. Scrolling a few pages and I saw a game from 2022. But I do not really know how rapidly this list changes, as I do not regularly look at it.
