(not sure how far im allowed to show those tbh)
if u click on user cp top left, u end up on a page that shows all your infraction's.
there should stand how much points u actually have at the top, and if they are expired, pretty much like here(mine) :
u clearly see i have 4 points, but they expired, so they do not count.
they do expire after 2 weeks, from what i heard, so just dont do shit until most of them expired.. then ure fine.
