its a glitch when you upvote, instantly reload, remove the upvote.
but it total it is counted to 0 globally

ah interesting, page caching is the cause of this (cached as "0 ups" but then removing your vote decreases it)

should be fixed now

Yea that's kinda like what I thought.

yea

You can't, you just upvote a comment load something else then go back to it and remove that upvote, that's how someone got -1 upvotes

it happened to mine
