Most Helpful Girl
Once certain users reach a high enough level of popularity, they start to get more and more support from other users. These more popular ones can start pulling the stupidest shit out of their ass in questions/opinions that they leave and even though it has next to no substance, these loyal followers that they've recruited, in a sense, will play along with it and act like it's the wisest/funniest shit around.
Hence leading to an ego-boost for the popular ones, and the cycle will continue.1
