@tillkkawa @NGreentail That's exactly what I was thinking. There's no way to genuinely know if someone used 3d models or not without some sort of speed paint, so I doubt this dumb rule would change anything.
@the_king_pale no, dont remove them, instead
create a new mii, their ideal partner.
do your best to make sure they become a couple and marry.
when they decide that they want a baby, remove the partner before they get the baby.
the mii will know better than to disobey next time.
