quoting a definition:

The implication behind the use of the term is that instead of a "true" or "natural" grassroots effort behind the activity in question, there is a "fake" or "artificial" appearance of support. It is increasingly recognized as a problem in social media, e-commerce, and politics.

Some groups accused of astroturfing argue that they are legitimately helping citizen activists to make their voices heard.
