If it were about the cleansiness of the bowl then I'd expect the bowl to be far worse. There is currently some sort of growth and I'm refusing to clean it in hope that dorm mates do though they are probably hoping for the same thing.
Just put some baking soda and ammonia/bleach into the bowl and run for your life. Unfortunately you will no longer have a bowl to clean or sit on;now you will have to sit on top of a hole.
