As always when mega corps are involved we have to at least entertain the idea that their employees and agents come out in full force to defend the actions of the corp. Anything else would be dangerously naive.
At any rate, the idea that companies with people who would collude in such a major way don't have any employees willing to manipulating discourse on a site like HN... that doesn't even pass the smell test, there is no way that this is the case.
This site should have all votes and flags by all accounts made public. No more guessing, no more squirming.
