okay so gonna agree but also defend :S
The first big one, 100%, like there is this one game that has "Lesbian content is made with the assumption it isn't NTR."... like bruh.. if you wrote it in a way, that it is NTR... then it is NTR XD
Or calling polyamory (lesbian sharing + MC) harem, when it is clearly not.
That community tags idea is a great one btw... but don't think the f95zone mods would appreciate that one. (sounds like there could be a lot of fuckery with people being trolls... e.g. you hate or love a certain genre and decide to stir some shit).
Although you can report a thread and say it is missing a tag.
Now for the defend,
Anyway, the wording is important, to quote "All the females will love you, but they are also okay with doing stuff to each other to please the mc." the emphasis is "to please the MC" which implies that they don't have interest in eachother, and are only doing anything because MC derrives pleasure from it. (e.g. rubbing MCs dick between their tits for a tame example, or one eating the other out while MC pounds em from behind for a more intimate example).
So as long as the dev is actually true to that statement then there should be nothing that is not harem (like an LI using a strap-on on another LI, don't matter if MC enjoys it, that ain't harem, that falls under lesbian and sharing).
So hopefully, they will make the more over the line of harem things optional, or more appropriately, simply not on the harem route.
My concern would be more with the planned futa, since it isn't specified if that would be on the harem route or not, only lesbian is separated. Could just be they haven't thought about it that much yet, but futa on female obviously has no place in a harem route, not even as a choice, assuming the harem route is its own proper fleshed out route, and not just a route you can get by making certain constant choices. (which I wouldn't do the latter, since players who want harem only route, probably wouldn't want to be constantly reminded that the LIs are willing to be shared, or want a futa dick.. kinda ruins the whole idea that they only love MC if you constantly have options to do otherwise in their face)
