Agree, that kind of specific behavior is really not cool. I think though the idea of trying to uplift or bury a story through organized voting is fine.
Bury. If you find stories with bad links, off-topic content,
or duplicate entries, click “Bury.” That’s how we get the
spam out of the system and let the good stuff rise to the top.
Other than that, they're pretty sketchy on what exactly it does.
