Only those who actually post something should be allowed to vote on other posts.
Simple. There is 7 douchebags (and moderators doesn't allow me to reveal their names) who downvote other people without even reading what they post, but doesn't post anything themselves.
They are toxic and useless people who slowly, but surely makes these boards into unpleasant place to be.
So, i propose that people here should be allowed to upvote or downvote others only if they have posted anything in the last 3 days. If they haven't posted anything, then they shouldn't be allowed to rate other people.
