Eh,
who cares.
I usually check out all posts by a person if I am curious on their profile, and if I want to get to know them better I just read. Rep doesn't matter much to me, although I try to return it when I get it. I do hand out the negative rep anytime I want w/out hesitation, one I don't care if I get it back, and two it is a way to voice my opinion that may otherwise flame and derail a thread. I always get a laugh outta the people that get all pissy about it.
There are a couple of folks that have full on red bars, and you wonder if they tried to do that and if people just keep giving them neg rep because they think that is what the person wants or what. In fact just talking about that now on some other thread. The anti christ and icmag douche, it's fucking funny I think.
