Risking violation of "don't feed the trolls" here to reply: that seems unnecessarily harsh. FTR I'm not downvoting you any further, but responding in case you have more specific and articulate criticism to level.
If you're going to make this sort of accusation, you should link to the thread so people can make up their own minds. With linkless insinuations, the actual story is usually significantly different from what is being insinuated.
The problem with astroturf accusations is that they are all flamebait (even if true), off-topic meta noise (the point stops being discussed in favor of the commenters), and worst of all unfalsifiable (how do you prove you're not a shill?). I've been spending a lot more time on political boards as of late, and I've yet to see accusations along these lines be even a net neutral. On balance, they're always bad.
