i'm doing data mining for arabic wikipedia to see what's there in the metadata and i came up with the blocked users who's trying to damage the arabic content by adding inaccurate information without any source or trying to flame persons. This is phase1 for now and i'm working to get different results for other areas like modification behavior based on what's going on in the real word.
