PS for other users : What I did is :
1° / Go in you admin panel, in Gestion > Users, and write/see the UID of the user(s) you want to set the reputation to 0
2° / Go in a terminal, and write :
# mongod
> use <yourdatabase>
> db.objects.update({_key: "user:<uid>"}, {$set: {"reputation": 0}});
> db.objects.update({_key: "users:reputation", value: "<uid>"}, {$set: {"score": 0}});
That's it ! 🙂
