I know that as [member="Brennan Cabrol"], I could not view the content of this faction while trying to click on the post my alt had been tagged in. I guess the settings of the forums are set to be read and viewed by members only? I dunno, it's been a while since I last used the faction admin side of things but I'm pretty sure you can make the faction public (which means other people can find it on the list of factions on Chaos) while the content itself can be set to private or otherwise deeming only members viewing faction business etc...
...If that makes any sense to you.
