I have an idea that we can reveal those post receiving positive karma and let negative karma undisclosed. That way, revenge from negative karma receivers would be avoided while publicity of positive karma restrains people from abusing it.
Actually we need to control not only about positive karma but also for the negative karma.
Negative karma can drop someone's reputation. Moreover if a bounty manager don't accept for the participants with negative karma.
My point is: It is no problem if negative karma is given to those who deserve it
but I am afraid if it is misused. Irresponsible people can do it any time without the right reason. We also should punish the irresponsible people. And make a strong regulation about this.
