As it appears everyone want to be able to have gang wars and mass shootout when they want, the idea of controlling them is bound to fail.
As criminals are the backbone of this community and considering the amount of players concerned, we won't have enough ressources to monitor everything.
Therefore, everything said by me before is cancelled.
If you want a gang war, go for it. You said you are criminals, then act as one and fight with honor.
If you lose, we don't want to hear any complain. No one is forcing you to take part into those shootouts.
When people will realise that most of the time when the shootout starts, one leader is running away to save his ass rather than fighting with his "brothers", they will maybe stop following him.
When everyone will be bored to spend their money and time into shootouts, they will maybe start doing something productive.
Have fun.
PS: Everyone is still supposed to follow all server rules.
