I agree like never before, especially with this:
after admins say " the following player will be punished" nothing really happen
A typical punishment I always imagine is following:
Admin: Hello Saddam, you've been reported by European_pacifist for breaking coprules. You shouldn't have planted the bank and exploded it with all the criminals inside
XX_Saddam_Hussein_XX:....
Admin: According to my duty guidelines and the infraction code, I have to give you 2 more infraction points. Would you like to appeal your infraction?
XX_Saddam_Hussein_XX:....
Admin: You have been given 2 infraction points for breaking coprules. You now have 18 in total. If you continue behaving this way, you will be banned within 60 years.
XX_Saddam_Hussein_XX: ananen sikerim
I have earlier suggested Mike implementing something like a short exam on coprules knowledge for police applicants. Tightening infractions should also be considered.
Imo, these should be the minimum points:
