Attractiveness is a subjective thing and not entirely a hive-mind thought process like most would have you believe.
It really all relies on people's preference. some might find you attractive while others not so much
It uses a machine learning algorithm trained with data obtained from a survey with a huge sample size. It's pretty accurate - the results within 1 point of the actual average score (on a 10 point scale) 95% of the time. So yeah, you ugly.
