Give feedback pliz who lowered karma.

Recently, I published several topics that many liked (about +30, was even for +60).
However, the karma was reduced from 33 to 18 and it continued to fall.

Since there is no mechanism, to indicate the reason - please, share your motives why you did it.

Trite insulting, and lost the desire to write. Is it so accepted, quietly minus?

I myself put pluses very often in karma. Cons - only hammam. Malignant. And only occasionally someone infuriates.
