Minusuem habrakarma

A similar post was already in my personal stand-elon blog. He appeared there when I had negative karma and I could not write here. But quite unexpectedly, my karma (I think not for long) came out in the "plus". The bottom line is this: while reading Habr I often meet this question: why are we minus? In some cases, everything is clear, but there are posts that are minus for completely incomprehensible reasons. And minus not only posts, but habrakarma. Maybe it makes sense to introduce regulations on minus / plus posts / comments / karma. Or at least just karma. Those. if a person has decided to minus my karma - let him say for what.
