"Astroturfing is the practice of masking the sponsors of a message or organization (e.g., political, advertising, religious or public relations) to make it appear as though it originates from and is supported by grassroots participants."

Are you saying that I'm an agent of some larger organization and not revealing this? If not, what exactly do you mean by 'astroturfing'?

And why will you not take me up on my offer to talk about this? Does it not concern you that you may be making a false accusation?

It's cowardly and rude to make these kind of accusations without even giving the accused person any kind of opportunity to present you with evidence to the contrary.
