BadWareBusters.org is a
platform for the further development of StopBadware's strategy to bring together people, organizations, and data in new ways to fight back against badware. The site already offers a pretty neat user reputation and message rating system, but we plan to build on this to provide tools that allow the community to express its collective voice. We want to learn from our users, so that StopBadware's research and advocacy activities can be as effective and current as possible.
In addition to helping users with badware problems on their computers, the BadwareBusters community has helped webmasters of sites that have been hacked to distribute badware.
Note: StopBadware is a project of the Berkman Center, where I'm a fellow.
