Unofficial factions are a difficult subject, as there is no guarantee whether those groups will exist for a long time (and thus deserve an entire page) or not.
Just have a look at the "Unofficial factions"-thread in the RP Factions forum here, and you will see that there are tons and tons and even more tons of unofficial factions, mostly existing for one or two weeks only (!).

True enough, but I figure if one's willing to go to the work of actually making the page (and have it contain some actual information), there's a decent chance of it sticking around.

I figure it'd probably come down to space constraints, really, so long as such factions were clearly labelled as unofficial. But I'm not the one making that decision, and I have no idea how much space is available for this.
