Fanboys who get angry when some one points out that a certain mangaka takes his readers for granted and while some of his ideas are innovative and great, the stories are really not that well rounded and deep as they believe.

Fans who get angry when someone points out that the art style of their favourite is not eveyone's cup of tea and the arcs are kind of repetitive after a while.

Members that take the website for granted, and believe they own it because they once upon a time registered on it.
