Astroturfing is creating a grassroots appearance when no such grassroots movement existed previously. Money doesn't have to change hands as directly as you hint at, and certainly not 'if you're compensated for broadcasting a statement'.
Here's the difference: Astroturfing is also the term for when a well-funded interested party creates and funds a 'think tank' or 'activist group' that has the unstated mission of forwarding their goal. The astroturfing group can recruit people that share an interest, track membership, fund gatherings, push information to assist their membership, and promote spokespeople without giving any of these people money. Every person that appears on behalf of that position has their activist efforts easier due to all these little helpful moments, but can be completely unaware that they're 'funded'.
A mob that splits the work and cost among many members to lighten the load, and lacks deep pockets behind the scenes is a 'grassroots' organization.
An org with deep-pockets supporters lightening the load is astroturfing.
Having (insert celebrity) call attention to your case isn't astroturfing.
Having (insert celebrity or wealthy benefactor) provide substantial direct funding is astroturfing.
There are many shades of grey between these two, but I'd venture that a key detail is whether wealthy benefactor(s) want to use grassroots' perceived lack of economic motive to hide an existing economic motive, and/or to hide their financial backing.
Sorry this went long; am interested in the topic-- I'm willing to concede this was written ad hoc, so other views / opinions are welcome.
I just occasionally see 2nd-order astroturfing firms (for lack of a better term) out there that do as I've described: surround themselves with unpaid teammates and pretend like they're so good at all the hassles of a campaign because of supporters or great karma, rather than the cash that funds all the background efforts that otherwise would take considerably more volunteer supporters.

Heh. We all can have fun mocking the "social science" sort.
But there's the perspective of the old wise crack, attributed to various singers (Louis Armstrong, Bill Broonzy, et al.) when asked if what he was singing was folk music: "I ain't never heard a horse sing a song.".
Similarly, all known science is done by gangs of humans, so it is inherently a social construct. Various historians of science have elaborated on this, by explaining that the scientific method has been rediscovered many times in many societies, but only one of them has developed a successful "science". The reason is that, in all the others, scientific methods have been developed by very small groups of people, typically in a "guild" or sorts, who hold the information very close and don't share it or their methods with outsiders. Eventually a small group dies out, and their knowledge dies with them.
The founders of modern, Western "science" developed not because they also discovered scientific methodology. Rather, their success was from their process of open publication. This enabled the "standing on the shoulder of giants" phenomenon, as Isaac Newton put it. But even that quip wasn't original with him; he just found a more elegant and memorable way of expressing it than his predecessors. It was published, so we remember it. With open publication of methods and results, Western science became a social construct that slowly spread to a large population. With that population, plus all the published material from previous generations, it all snowballed into the world-changing system that we see today.
No single human could have ever done this. It required a social system, with massive sharing of information. Calling it a "social construct" is merely an elegant way of saying all this. It's why modern science has been so more successful than previous local, personal development of knowledge. It's also much of what gave a small, local population on the western fringe of a continent so much control over the rest of the world.
As the biologists have been telling us, the dominant species tend to be the social ones. And it's their social behavior that makes them win over their less-social relatives. We see this within our own species with the sub-population that developed the social construct that we call "science".
Of course, I wouldn't deny the fun we had when Alan Sokal managed his publication feat. That was hilarious. Nobody says that social things are always correct. The history of science is full of mistakes and dead ends. Open publication means that society can learn from them, and not repeat them.

It's long been true that a top reason to go to academic conferences isn't only for the paper presentations, but rather for the hallway/dinner/bar conversations about those papers. More formally, many scientific journals will publish short letters or commentaries about papers they've previously published, and that practice used to be even more widespread (at some journals a "letter" has morphed into a mini-paper, but they used to really be letters to the editor).
The same is now true online with something like Terence Tao's blog [wordpress.com]: it's interesting as much for what other mathematicians post in reply, as for what Tao himself posts (though his posts are quite interesting). The main difference as I see it is that the number of people participating is much greater (which has good and bad parts), and, in comparison to hallway conversations, the conversations persist and get referenced back to more, since they're in a semi-durable written medium (that's the "wiki-like" aspect the article discusses).

“Anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that 'my ignorance is just as good as your knowledge.'”
The amount of effort required to parse through comments to find gems of significant value is enormous. I know that this is that age of the crowd and so on, but there are certain issues on which the opinion of the crowd has on average very little value because of the complexity of the topic and the years of experience required to make informed conclusions. The trade-off between expert opinion and open crowdsourcing varies widely depending on what is the topic under discussion, and the userbase of the particular site.

Since "science" cannot prove historical events, the only thing left is opinion. By definition, if something is repeatable or testable, it cannot be "proven" by scientific methods. All you are left with is belief.
It'd be difficult to find a more misleading characterization of science.
First off, as various historians and theoreticians of science have observed, scientific methods rarely (if ever) "prove" anything. Scientific methods are all based on 1) proposing explanations for observations, and the 2) attempting to disprove those explanations. After sufficiently many such attempts at disproof have failed, an explanation gets promoted to "hypothesis", and then to "theory". But these are only tentative, with further attempts at disproval continuing whenever anyone can come up with a new test that hasn't been tried.
As part of this, an explanation that is untestable isn't considered scientific at all. It's neither true nor false by scientific standards, until someone comes up with tests that could possibly disprove it. Some explanations (e.g., "God did it") have remained in this state for centuries.
Actually, there is one situation where there is a sort of scientific "proof". This is dealing with negative claims of the form "There are no X".A canonical example is the old "There are no Black Swans". This was disproved by the discovery of a species of swan that is (mostly) black. It lives in Australia, so at one time it was Unknown to Science. You can rephrase this in the positive form, "There are Black Swans", and such existence statements can be "proved" by simply presenting examples. But this is generally classified as data collection, which is understood to always be incomplete. And such negative claims are generally not taken seriously by scientists unless you can give good reasons why X can't exist, based on previously accepted theories. Even then, a single (non-fraudulent) example can suffice to shoot down your reasoned argument against X existing.
In any case, "proof" is something done by mathematicians, not scientists. If you reject science that doesn't present proof, you reject all science, since proof isn't what science does.
If all you have left is belief, then you are susceptible to being defrauded by anyone who comes along with a new belief. But history shows that science's testing process has been pretty good at disproving most beliefs. In the process, the leftover ("not disproved") beliefs that fell out of the process have led to all the technical advances of the previous several centuries, something that the earlier purveyors of belief systems ("religions") have failed to do for as long as we have recorded history.
