You're derived from monkeys. Your monkey brain compares your standing in social hierarchy to your peers. If you are better than your peers your monkey brains shoots chemicals that make you happy. If you are worst off it either shoots ones to make you feel bad or shoots none at all. The other monkeys want to see someone within their social group fail because it betters their position.

My suggestion would be to try to stop being a monkey by refraining from visiting the threads or realizing how irrational the behavior is and hence stupid to engage in. Or in other words stop getting your panties in a knot and get a life if you care 2 cents what any random person thinks.
