Then you are contradicting yourself.
I'm just curious, why?

What is with Reputation or Karma that is makes some people interested? You really care what other people on the internet think about you? If Facebook had a system like that, and you had a bad number, I'd understand that feels shit, because those people know you
personally - well, in most cases - and you have an actual contact with them.
But here? I mean, it's a forum, you don't know my voice, you don't know how I say things on a forum, I'm mostly sarcastic for instance and that's hard to understand through typed words, do you get what I mean?
Besides: it's worms.
