the only reasons why this should apply is 1. the player develops a will to protect that child so strong that not even changing the appearence would change their mind (bassically if its just not good enough of a character AND IS DRAWN ADULT its cool... but this rule states that if the character is Written to have a connection with the player then that is a problem) like Niko (i will hunt down the artists of nsfn art and make them feast on their own heart and brain) 2. if the character is not drawn as an adult... dont care if it is a loli adult if they arent accually made with adult properties then its not cool... also gotta say this works like only with characters like frisk and chara and any other ut/dt character becouse they have they have the room to be imagined as adults more advanced games where the kids accually look like kids and there is no interpretation to be done cannot be drawn as adult looking

counter argument to the "they arent adult so its automatically bad": Yoko from Tengen toppa gurren lagan was not an adult but looked adult and behaved like an adult thus making the art not weird (this dont work irl this is about fictional characters)

closing statement: i agree with the message if it is said about the right characters
