What can create conflict is knowing which user gives negative karma to another user, it is something that could cause problems and create a bad atmosphere in the forum. A few weeks ago the admin said he was working on a system to show a karma counter (positive and negative) for each post separately, that way we can know which posts are most interesting to the community. It is something that has not yet been implemented, but when the time comes it will be very useful to find out what is most interesting for users.
Not only which posts received the most +karma, but also those who received -karma. It will be especially useful to detect the abuse of karma, because currently there is a possibility that someone gives negative karma to a user for no reason at all, without the user notice it at all. I already wrote about it, by following someone's activity in a certain period it is possible to cancel every positive karma with a negative one without the user noticing it at all.
There is also no doubt that there is abuse of positive karma, because recently we had several users (all new accounts) who shill a certain service and someone gave them positive karma for classic shitposting - which means that they had a Senior+ rank that they used for that activity.
The sooner we get that feature, the better for everyone.
