the principles of karma are:
- positive karma
- negative karma
who can do this, obviously he must be at least a full member account and above, below that he can't do anything with karma, but he can accept karma.
positive karma
Everyone has their own criteria with or to others and may not the same, even though the purpose of positive karma is to provide incentives so that he will make a good topic or at least a constructive response , but all of that becomes relative because the criteria may not be the same, on topics and responses. So if we are happy with someone both through topics and posts but other people are not, it's fine if we want to give karma. remember the karma we get we don't know from who gave it.
negative karma
in principle it is the opposite of positive karma.
but those who have karma should be wise and kind and be able to take responsibility for what they have in order to be used as well as possible, is it impossible that someone will abuse it !! clearly possible.
all back to the individual.
