As we all know from the physics course, temperature is interesting in that it seems to be unrestricted from above, and bounded very clearly from below ( absolute zero temperature ). Why would we not limit the minimum value of karma and habrasila on the same principle? Then there will be no such thing: " I am the coolest troll of this dreary resource. I have copper eggs. And I laid *** on your miserable minus " or " It is better to be minus first than 2043 ". Also, having seen that a person has so many drawbacks, people will not add one more to them, they will better go and put someone else a plus (I hope =)). I don’t see the disadvantages of such an innovation (you see? Write it in the comments), but technically it is quite simple.
