MIT has a new tool to combat online harassment: your friends - The Verge

The tool is called Squadbox, and it “friend-sources” for moderators to filter messages and support people who are being harassed online. So a blogger who wants to have a public email address to receive tips, but also wants to avoid receiving hate mail from strangers, can set up a Squadbox account, and use two of her co-workers as moderators, MIT scientists propose.
