top houses / not top houses

I just looked at the sororities' individual pages and found that many houses had more than one untrue and horribly negative post on them. The interesting thing was that the top houses all had negative statements but (at least at this time) there was no one defending them with a reply. Only the lower houses had someone on to defend their houses against negative comments. I guess that goes to show the level of self-confidence in the top houses.
