That is complete utter nonsense. I've played a couple other vn's similar to this, that had underage characters but they were simply part of the story or a side character, no lewd events or context involved with them. I've always played these NSFW games more for the storyline and character progression over any other reason, lewd events are just a bonus for me. Patreon seems to be getting worse and worse with the censorship and regulations, I won't be surprised if they eventually outright ban nsfw games entirely at some point. What a shame
