Astroturfs can be described using synonyms such as fake grassroots, simulated public outcry or manipulated public opinion. Astroturfing is a form of deception in which a group or individual creates a false impression of a widespread grassroots movement, while actually having few supporters. The purpose of astroturfing is often to manipulate public opinion or sway political decisions. Other synonyms that are used to describe this practice include pseudo-grassroots, manufactured dissent and fake support. Astroturfs can be difficult to identify, but with increased awareness and scrutiny, the public can better distinguish between genuine grassroots movements and astroturf campaigns.
