Edmunds.com, a resource for car shopping and automotive information, has filed a lawsuit against Friendswood, Texas-based Humankind Design Ltd. for, among other things, fraud and breach of the Edmunds.com membership agreement.

Through its review of every car dealer rating and review submitted to Edmunds.com, the company discovered that Humankind attempted to register over 2,200 fake members on the site and tried to use them to create fraudulent content to sway car shoppers’ opinions of dealers.
