Walt Whitman gave himself positive reviews under aliases. Good to know "fake reviews" isn't a modern thing, apparently.
It's not so much the fake reviews that annoy me, as much as the bandwagon effect that follows. Going with the Walt Whitman example, if someone tried arguing his work wasn't very good, he'd be shunned from literary circles and nobody would ever take him seriously as a writer/critic.
So basically, if you dupe the right people, you're untouchable (Otoh, a concentrated effort of negativity can probably as easily ruin careers).
Sure, the "think for yourself" trope is an obvious retort, and in a world of no stakes, that's good advice. But sometimes, mass opinion matters.
Why does it seem like individual people are often smarter/less niave then a group of them? You'd think more people = more critical thinking, but it really doesn't work that way..
