There is another problem regarding negative karma (karma war).
There is a section to report such activities. If you are given a negative karma and you think you don't deserve it, then you can file for a review at Forum Court. Instructions https://www.altcoinstalks.com/index.php?topic=13683.0
There is no info regarding negative karma on member profile. There is no feature like that, not yet.
✓ For example : user who have more than 20 karma (and he/she do not remember how many karma that he/she has).
Then , there is fraudulent user attack her/him (give bad karma) , just because of different point of view on the forum, and or personal life problem.
The victim don't know he/she has already got negative karma.
✓ Second example :
S : scammer on the forum
N : nice member
1. "S" is keeping to break the rules, repeating shitty post and copy paste.
2. "N" find his (S) post, than inform or give warning to "S" regarding his mistakes.
3. "S" don't like the warning from "N", then "S" send bad karma to "N".
4. "N" do not know he's already got punish from "S".
5. So, he don't do report on forum court, and do not want to send pm to Admin, because "N" guess he already got negative karma from Admin , not from "S".
