Charges of Karma

Question

Habr

Why are karma charges spent when trying to raise karma to someone who cannot raise it?

Well, for example, I have “25 votes for karma”, I go to% username% with karma 0 and give it a plus in karma.
I still have 24 votes for karma, and %username% karma becomes 1.
Immediately, I again click on increasing karma for %username%, his karma does not increase (1 remains), but the number of votes for karma remaining for me decreases by one unit.

Is that how it should be?

Answer 1

Obviously this is just a small bug.

Answer 2

I decided to try on your karma. Raised by 1 point, their number fell by 14. Such a bug.

Answer 3

Some kind of well-wisher burned my karma one by one for several days in a row, until he halved it. Habr is his judge, but did this gentleman get at least something other than moral satisfaction?
