Yeah, automatic voting gets dangerously close to automatic censorship and botting.

Also, human language, context and nuance is complicated and the unknown error bar on "correctly flagged posts" scares me. It's not entirely predictable what kind of posts people may make, and accordingly not entirely predictable what the plugin would and wouldn't recognise.

A post chain "Madness?" / "THIS" / "IS" / "SPARTA!" may make sense and be fun in the right context, but the "THIS" comment could get botted to hell.
