I understand its a free product but encouraging your *mostly* underage fanbase to make alts to review your game so they can save their favorite fictional character honestly feels like a sick joke, espically since this can result in their account being perma banned.
Agree with you at every other point but i don't think her fanbase is mostly underage especially based on the other games that are more for adults. Sure some children might be there or ignore the warnings and age restrictions but you kinda portray it as if she knows the age of her viewers and is using that in her advantage.
Again i agree with you on the other point but the audience is not something she can control especially on the itch.io page and also when Youtubers with a large minor audience (or just those who don't age restrict) play her games that may be not nsfw enough to get age restricted on Youtube but it's still for an actual older audience.
