What I still don't understand about Facebook is that they're letting people charge money for Groups, yet the same very strict content guidelines still apply. Paying adults are unable to have "adult content" of any sort on the site (and their definitions are very broad) but hate speech, Nazi propaganda, radical right wing extremism, and out of touch conspiracy theorists that harass tragedy victims are allowed? Facebook continues to confuse me.
