Player Factions listed on the wiki was always a debated thing even back in 2238. Some devs did not want them listed on wiki at all. The problem is...factions fall [so easily] into inactivity, that how will we know when to "delete" them from wiki?
Maybe this requires a new rule: only a faction's leadership can add such a page, and they must have some sign on the page about their activity level. If not, it should be understandable that the page gets deleted.
Or not. Just delete the ones we think are inactive, because wiki allows changes to be reverted. If one gets wiped and someone cries out, then undo the change and BAM! page is back.
