Game accepts fanmade AUs. Yay! But game does not accept personality swap AUs? Well, of course not. Completely understandable. Game proceeds to accept Homestuck bloodswap AUs? Are you fucking kidding me. That is all bloodswaps are. They take a character and swap around whatever aspects of their personality that the creator decides would be affected by their blood/text color. But I guess because it obviously changes the appearance and history of a character that suddenly makes it a-okay?
