That said though I really dislike the atmosphere created by frequent shill accusations. It seems to rapidly create an echo chamber, where minority opinions are dismissed.
'3rd parties' who spend any amount of time here are perfectly aware of that a pro government, anti-Snowden point of view won't be popular. I doubt they would turn tail if someone suspected their presence.
And arguably, false positives and arguments about whether or not someone is a shill work in favor of actual shills. Notice how nobody ever seems to accuse the people making those accusations of having ulterior motives, despite the fact that a false flag strategy of deflecting attention to innocent accounts and derailing threads would be a much smarter strategy on their part than sockpuppet accounts making obviously noticeable propagandic statements.
Then again, I can't help but wonder why people bother asking if someone else is a shill, as if they honestly expect an actual shill to admit to it. Probably the same people who think undercover cops actually have to admit who they are if you ask them.
