Maybe, but you already said that it didn't feature explicit loli or shota content, therefore I don't see why it would be banned. It's more likely that it's improperly tagged or that you conflated something and we're searching for the wrong thing. Still, keeping the thread bumped is a plus and someone who knows what it is may eventually show up.
Let's review once more.
1. It's a Japanese game, likely made in RPGM, with an English translation that could be MTL for all we know.
2. The protagonist is an ordinary woman (not futa or furry) and starts in the company of a friend or her significant other, who is male. She has dark and long hair and normal or above bust size.
3. They start in some kind of desert or sandy place. In any case, the tileset is brown.
4. Along the way they meet other people that join their party and/or cause. There's at least 1 other man and a few other women.
5. The game features classic turn based combat and a lewdness or arousal system that can affect the party. It features either combat molestation or outright rape too.
6. The game has a day/night cycle that's either accessible through resting or by a real time clock.
7. During the night, not initially but eventually, the feMC may prostitute herself, and in the future she may convince her party members to do the same. Unsure about the male ones.
8. The game has 2DCG.
Is there anything else that you might've remembered or did I say something wrong? I'm pretty committed to getting to the bottom of this now.

1. the game was japanese style, a typical RPGM with anime style art (i expalin better in point 8), i have the impression that it was made by a japanese company in japanese and then translated
2. the protagonist is an ordinary woman, probably with some magic skill or half demon /succubi., but the appearance was of a woman. there are no furry in the game there are some monster/beast and magic (but was not focused only on magic)
3. one of the first zone is a dessert, tileset was sand color. i do no remember if the travel was desert-first city-desert, or you started in the city. you can access the desert area from the first city, the city was divided in zone and to move to a zone to another you needed to load the new map (like when you enter through a door), there were other city and i am pretty sure you couldn't reachthe cities walking but via fast travel: ship or some kind of teleport. from the first city you could go in the external zone of the city.
4. i do not remember the formation of the party, probably the party was full from the start and, most probably, all other members ware on the same level (friends/companions level), there wasn't a preferred or loved one at the start.
5. all correct, but more than rape it feel they were complacent, i think you could arouse the enemy too
6. yes, i do not remember if you need to go to sleep or the time flowed
7. yes all correct
8. yes, the art style was similar to "Samurai Vandalism" and "Cattleya's Report", the artificial sensation of the art was 0. instead was different than "Time Traveler Marie" and "SENGOKU SLAVE"
i remember than the rpg part was complex, probably there were classes too, but for sure you need to think and you couldn't just go straight and autoattack. probably there were different difficulty level
another thing i remember is that the death was represented at the sprite level, when you raided the church there were some skeleton, it was a little raw and violent.
the body types were proportional
there wasn't: gay-homo content (there was lesbian), guro at the 2dcg level, excessive torture, furry, futa, incest (the party was not blood-related, 90% sure)
