making it so bad that it must be change is the wrong attitude. Human beings will do everything to optimize. bot voting is optimization at its best. Optimization does not care about intent, or whats wrong or right. So you have to first think about how you want the best version to behave. It would be such that people's vote needs to be genuinely based on the content. The only way to do that would be to require that people scroll down the entire thing before they are allowed to vote. People will try to optimize this routine as well by creating code that does this automatically. But at least it slows down the time allowing real readers to get a chance to get in line. but then that detracts from the users of feeling freedom to vote however they wish, so perhaps you allow people to vote from the homepage, but that vote is worth less.
