There is something that i don't understand in the pbban philosophy, something of wrong.. and i try to explain what i mean:
from what i understood pbban ban the cheaters, like the police arrest the delinquent for homicide.
So, for example, if someone kill a person using a gun, the police arrest him forever.
Then that gun been reselled by auction from some agency.
A people buy that gun (without do something of wrong)... so the police go to arrest him for homicide because he bought that gun?
Another example... a black man kill a people, so the police to prevent others kills arrest all black peoples???
I think that pbban have to punish the cheaters, not the owners of a game.
Here, in my contry, we call this behavior unjustice... but if for you this is fair... i don't know what to say..
