How does karma system work?
When a question or answer is upvoted, the user who posted them will gain some points, which are called "karma points". These points serve as a rough measure of the community trust to him/her. Various moderation tasks are gradually assigned to the users based on those points.
For example, if you ask an interesting question or give a helpful answer, your input will be upvoted. On the other hand if the answer is misleading - it will be downvoted. Each vote in favor will generate 10 points, each vote against will subtract 2 points. There is a limit of 200 points that can be accumulated per question or answer. The table below explains reputation point requirements for each type of moderation task.
