Micro-astroturf?

Ted Shelton at IP Inferno has written a couple of interesting posts, speculating that some of the telco-apologist comments he's been getting in response to a piece on net neutrality may actually be a coordinated effort by astroturf (i.e., fake "grass roots") lobbyists. He may be on to something, he may be mistaken, he may be paranoid, but it raises an interesting question: how do industry lobbyists reach people in the age of the Long Tail? Seems obvious enough to me that anonymous/pseudonymous blog comments and participation in online forums would be an ideal strategy.
