As we all know building a community is hard especially when it's new. I've heard and been told by other website/community mods that Astro Turfing is commonly done by many to help build and encourage people to join in.
For anyone that hasn't heard the term before it's when mods make their site look like it's being used, either by posting on the forums or contributing to the site in some other way as other users. In essence building a fake Grass Roots "Astro turfed" movement. New communities commonly face this problem because potential members don't want to be the first to post and don't want to post in a community with nothing in it.
Is it ethical to Astro Truf your site? Have you ever used this method? What can I do to gain legitimate users who don't mind being the first to post?
