View and scan a private Facebook group's posts

[Info]

Hi all,

I'm a member of a private facebook group (it has 100k members, but still private), and I want to automatically scan every new post in this group.

My first thought was to use Facebook's Graph API but turns out it's really limiting in terms of permissions (it requires the group admin to install my app), so I can't use it.

My next idea is to use AutoIt's _IE api and basically refresh the group's web page every couple of seconds, then request the source code of the resulting page and scan it. This approach is way more technical and annoying to code but it's the best one I can think of.

Has anyone ever done something like this? Is there a better approach I'm not aware of? (doesn't necessarily has to be an AutoIt solution)

thanks
