If you look carefully, you'll notice that all those who have more stars than just one are members of OFPEC staff (admins).
The number of stars used to raise as you post count would raise. Like if you make 5 posts you have 1 star and when you've made 50 posts you'll get another star.
OFPEC doesn't support that idea anymore. Everyone is equal in here when it comes to stars or post counts.
