What's up with the thumbs down ?

I just went in and checked some of the answers I responded to in the last few months, and there are "thumbs down" all over the place - in almost every category

Not just my answers, but everyone's.

In some cases, ALL answers are given a thumbs down, but in others, all answers but one ... leaving no doubt as to who did the thumbs down on that one.

I know that they lose points for it, and fair enough.. but it's just so juvenile and it ruins it for people who are trying to do the right thing.

I will give a "thumbs down" if an answer is just a joke or is nasty, but never simply because the answerer disagrees with my opinion. We're ALL entitled to our opinions, and most of try to help in the best way we know how to.

I also give a "thumbs up" to answerers that have gone out of their way to answer a question with correct information or who have something positive to say.

Why doesn't *answers* do something about it - like keep a better eye on the people who are just playing games?
