Until you have up and down votes there always will be someone making a tally.

The concept of Karma of other sites, to be fair, is not as simple as that. A lot of times the Karma is not a straight tally, there are algorithms to mitigate abuse (ex. Try to disregard mass voting, sudden influxes of votes, or known bots votes), or it is used to indirectly move the conversation to a preferred subject (ex. Making points obtained in some discussions or communities less valuable, or directly not considering them).

Luckily or not that kind of Karma is not present here, which basically makes the whole concept of total Karma pretty useless because you really can't trust the value to be kind of truthful and not manipulated.

Already with all the anti abuse, and it being calculated in a centralized platform, it was generally worthless. Here it is completely worthless. People should just be reminded of its real nature of an easily gamed system, and that it is not what they were used to.

We can only hope that in the long run they will drop it.
