I have a lot of votes on comments on popular articles (50+ votes for each comments, even for dumb comments). All comments on thoses nodes have these silly votes, even rather recent comments (less than 1 month). They comes undoubtly from robots, even I have "Disallow: /vote/" in robots.txt, and all vote links have "nofollow" direction.
How can we disable those links for robots? For heavily cached sites, robots = anonymous users. Thus, I think the best way could be enable vote for only JS-enabled users. Will there an option for it?
It's an bug, as currently most voted comments are all from robots.
