I got a detailed response from ImmortalGoddezz, and to sum it up, talk pages really shouldn't be edited or cleaned up.
IMO, I think talk pages look bad because it sits right at the top of the entry and makes it seem as though Gamma Phi as an org is mixed up about things. I think that mistakes could be corrected without a talk page, but in this case if ImmortalGoddezz erased her information, information from other users on the talk page would remain, and that would make it look even worse.
I think it boils down to someone at IH monitoring the page and correcting mistakes as they happen.
