Use of one or more front groups is one astroturfing technique. These groups typically present themselves as serving the public interest, while actually working on behalf of a corporate or political sponsor. Front groups may resist legislation and scientific consensus that is damaging to the sponsor's business by emphasizing minority viewpoints, instilling doubt and publishing counterclaims by corporate-sponsored experts. Fake blogs can also be created that appear to be written by consumers, while actually being operated by a commercial or political interest. Some political movements have provided incentives for members of the public to send a letter to the editor at their local paper, often using a copy and paste form letter that is published in dozens of newspapers verbatim.
