Lock voting to only threads you have commented in.

Reposting my answer from a previous thread:

The reality of this situation is either the moderation team gets a lot more comments to moderate for value, or we get a lot of non-constructive comments: "I upvoted 'cause I agree." "I down-voted 'cause this is dumb and unbalanced."

There's not really a sweet spot where the community responsibly comments enough that moderation doesn't have to intervene, and even then we'd need to find a way to retroactively remove the vote if the comment isn't sufficiently adding to the discussion. It just isn't plausible.

Bug? Yep bug. Whole OP vanished, can't read or edit it. When I try to edit it, I get "error fetching discussion to edit".
