Comment on Show HN: A Way To Hack HN's Karma

I saw this but don't really consider it much of a problem. It's the kind of thing that you can't really exploit. It'd be obvious if you really tried to use it for evil and then PG would kill your account.

Not necessarily. You could make the CSRF request on, for example, 80 percent of the views to make it look legit. You could even take a more sophisticated approach and start by automatically upvoting for 100 percent of logged in users just to get on the front page and dampening once your story rises in the rankings.

And if any users notice your account and domain are banned. Not saying it shouldn't be fixed but I doubt you would have much luck exploiting this at any scale.

If HN has some sort of redirect to any URL page (eg, redirect.ashx?url=http://www.google.com I don't know if HN does but a lot of sites do in some form) then it could be exploited possibly
