Is it actually necessary to weed out bot-clicks? If all sites have equal amounts of bot-clicks, then you can just charge 80% less per click (compared to the situation where all clicks would be human). Perhaps in practice the bot percentage changes widely per-site, so it's still important to have statistics on bot-clicks.
