I agree, I'm not sure if or why this is actually a priority, except when it comes to the victim's of flag wars. Many of which aren't producing bad content, or plagiarizing. They simply are the "bad guys" to the wrong whales.
Not that this is an easy answer but I think the priority should be to attract new users and let the flag wars continue, and hope those good content producers who have been chased off, are replaced by many new ones!
