Also, comments become unvotable after a while (I think a month).
I'll comment on a dead thread from the previous friday, rss feeds ftw. Say nothing particularly controversial or anything, a positive message.
Then I'll hit an active thread and say something thought invoking. I'll end up -10 on the dead thread comment.
Basically there are groups here which curate content using downvotes.
Luckily it only works against the last couple days. So HN is incentivizing you to only make 1-2 comments per day and no discussions are allowed. Which makes it easier for those curating content to do what they do.
Worse yet, when you get targeted like this a few times, you end up shadow banned on HN for 'low quality posting' but it's really just people curating content.
Yes - it does seem that way to me too. Someone doesn't like what you said, so they go the whole hog and downvote as many comments as possible! (4 another user says..) And then get their mates to do the same.
I'd at least like to know my stats - rather than the result - eg: If I 4000+ and -3999 all I see is +1... But it be so interesting to realise there was a lot of polarity to it.
Thanks for your thoughts.
the karma thing is ridiculous - I just want to know the rules/boundaries!
