In my experience with TF2, many popular community servers have common-sense rules like no slurs, cheats, etc. The great thing about a player-run server is that, if you want, it can be stricter than official guidelines, as Valve for example is pretty hands-off beyond the obvious in-game cheats. It allows pockets of the community to shape the experience they want to have more adeptly than official servers ever could.
