How do you get negative points on it should be impossible

It's probably because some questions you answered get deleted :/ i have the same problem

Explanation:

its actully posible it happend to me once. so if your acc gets banned or your questions/answers its will take away your points and you will be left with the number of points you had before it got banned or delted. so for example i had around 500 points so you would have to answer questions untill you out of the negative :)

i believe agnus organum.
