The Battle to Destroy Wikipedia's Largest Sock Puppet Army Link

It seems small relative to the size of Wikipedia, but it highlights the value of supporting them:

By September of this year, the investigation talk page included over 900 edits from more than 50 authors. It had unearthed 323 user accounts as confirmed sockpuppets with an additional 84 suspected. The only other known sockpuppet network of this size and scope was the case of Bambifan101, a still-ongoing investigation that located 236 suspected and 249 confirmed accounts. In other words, this was one of the largest—if not the largest—discovered sockpuppet networks in Wikipedia history.
