I was assuming po meant some automatic system. If you wanted to use humans maybe you could have moderators do it.

I agree that it'd be dangerous to let anyone tag. People on YouTube usually mark anything they disagree with as spam. Hopefully it wouldn't be the same here though.

After reading your comment I realized I've seen downvoted comments but I can't downvote. Is there a karma requirement?

[djcapelis]

Yes. After you hit a certain karma threshold a down arrow shows up and you are able to downvote. The specific threshold varies, but it's below a thousand and above a hundred.

"The specific threshold varies..." around 200 points if I remember correctly

[wahnfrieden]

500 now.
