That seems to be part of the game, and maybe is a tell about the game Lin is playing. Which is to say, Cultstate's overarching motive is to explain how easy it is to influence the public conscious online via information warfare.

Simply by "echoing" the existence of blackmail and its usage as an asset among the hegemonic class, whether having it or not, there's still a question as to whether or not you have it. Do you? Does he? Doesn't matter really. The fact that somebody, somewhere might just have it is likely enough to incite paranoia among this class to prevent it from operating effectively.

The networks enabling blackmail are incredibly discreet and based on a lot of trust (and, of course, blackmail). If 1,000 Lin Woods are echoing the existence of blackmail, and/or saying they've got it, then you could hypothetically disintegrate these trust networks and make them turn on one another. Forcing their hands.
