A tan should represent the board. loli tan was made by just one random dude long before anyone knew what /bant/ would be like, and it was consistently dismissed as shit by everyone until someone made something worse (Bantanna).
Stop with the pointless squabbles. Why select between shit or more shit? The true /bant/dit knows that there's only one character that fits the bill. The real /bant/-tan is Leaf Girl.
