Small-time voting fraud in the form of asking acquaintances to vote probably goes on all the time and frequently succeeds at securing a front page spot already; after all it only takes five votes or so. We occasionally see hard evidence of it when someone outright admits to this practice or solicits votes in the open on Twitter. People just don’t mind it that much because right now the practice doesn’t noticeably degrade the experience. Imagine if big money is suddenly involved at a much greater scale.
