Well if you look at internet community building at its core, its not unlike a company. When a company is small, things are simple and usually everyone is happy because communication and transparency is easy with its consumers.
However, when a company expands beyond a point of local administration, it becomes difficult to meet the needs of the entire consumer base. Microsoft is a great example of one such company that has this problem. Even in non-profit internet organizations like tf2center or stadium, there comes a time when moderation is an issue.
I like to use the old Latin adage "Quis custodiet ipsos custodes?" to describe these organizations, witch directly translates to "Who will guard the guards themselves?". If you look at scrap.tf, this is an example of an organization that has remained, for the most part, transparent and straight forward.
In conclusion,
TL;DR Maybe tf2center has become overgrown, and its garden needs weeding out?
