It is like warns on ingame acc, it helps us to decide how to punish you if you break rules again. So your warns are permanent but you can get "minus" points (so your watched status would disappear) for helping us or other users.
If you think you deserve those minus points, you can send PM (with links where did you help) to any admin (I think) but best would be contacting some1 from forum crew (me, Night_must_fall or Djerfi).
