Here's What a Warning Point Does:
1. It leaves a record for Staff to know why someone was warned in the past and gives a link to the content they were warned for if it was a post/discord chat/etc. This is useful for us in getting an at-a-glance concept of whether someone has been in trouble before, how often, and for what type of behavior.
2. It's a quick, easy way of letting someone know that the content they've posted is violating policy (and how).
3. That's about it. They don't stack up, they don't have any particular effect on whether you qualify for a moderator position (not necessarily anyway), certain things don't have a higher point value than others, and they don't affect the Staff team's decisions to ban outside of the factors that are considered anyway.
Warning points mean kaka in the long run. You can have fifty previous warnings and not be banned, or you could be banned with none at all. It's all about your behavior. So don't worry if you have a warning point!
