I really don't know what to do with that. Based on the description of the video, and after watching a few seconds of it, I closed it (because I really don't want to watch someone get beheaded), and then started to permaban Woolygimp (after seeing in his user notes that he's been suspended quite a few times from 2+2). However, Woolygimp pm'd me that the actual beheading was edited out. However, the video still really troubles me. I'm noot sure what to do with this one, I'm thinking permaban, based on this users history.
Edit:
This is the thread
I also think this thread falls under the "posts designed to forment hatred" standard.
Edit: I permabanned the OP. I watched enough of the video, and it showed enough to be horrible.
