It is fine to ask this question because based on tag rules: https://f95zone.to/threads/tags-rules-and-list-updated-2024-01-29.10394/ you are only supposed to add tags that are in the game. You cannot add tags that will be added in the future (see rule 2).You don't need to answer these dudes: the game has no harem tag.
Same with these ntr dudes: the game has no ntr tag. So why in the damn world they ask whether the game has ntr content and why you keep answering them.
Since the description in the first post does not include planned tags I think it is fine to ask the question to know if those tags will be added in the future. If you find it annoying simply ignore the posts.
