On this site, you can see every story somebody has submitted or upvoted by going to their profile. The comments someone up/downvotes isn't available publicly, but I assume it's kept on the backend. I think the noise in a simple upvote action is too much for any legal meaning though. You can't tell if somebody upvoted for agreement or humor (poe's law) or upvoted out of friendship (voting rings) with no cares at all. On Facebook, we know their upvotes ("likes" they say) are used for tracking and manipulating everything you do — informing your news, tracking you across the webternet, logging your interests. But, there too, the upvote is ambiguous. If you upvote "X died" does it mean you like that they died or you you're showing compassion? Now, with Slashdot moderation, user upvote could be more useful assuming the user isn't lying, but nothing supports slashdot-like moderation anywhere else. Ain't nobody got time for quantized sentiment decisions.
