Disclaimer: This is a vendor white paper. I am NOT paid by them, dont have any business relationship with eModeration either. But I consider Tamara Littleton a friend and community pioneer in the field of moderation.

The paper, Six Techniques for Safer User Generated
Content Campaigns, details techniques for creators of UGC sites to protect both
their brand reputations and their users; while creating a site that is fun and
engaging for users.  It makes
recommendations on how companies should: create guidelines on acceptable
consumer behaviour; filter content to avoid offensive, litigious and
hijack-marketing submissions, and how to deal with these submissions; support
moderation techniques with technology; enlist users to help with the moderation
process; create visible moderation actions to discourage users from abusing the
site; and develop usability test plans for moderation.

You can review the whitepaper, as did I and find some really good nuggets.

Thanks to Malini for pointing this to me.
