Good point. I imagine that detecting such behavior will also be pretty difficult. It's one thing in a forum, where you'd maybe want to discriminate against idiots (but that would still leave you open to the problem of shills/sock puppets). But for big companies like Google, would they really want to open that can of worms? Of course, there's a quite relevant xkcd: https://xkcd.com/810/ https://xkcd.com/810/
