"Astroturf seeks to manipulate you into changing your opinion by making it seem as if you're an outlier--when you're not."
"Hallmarks of astroturf and propaganda include use of inflammatory language such as quack, crank, nutty, pseudo, paranoid and conspiracy."
"Beware when an interest addresses an issue by controversializing or attacking the people, personalities and organizations surrounding the issue rather than the facts. That could be astroturf."
