Gun trade system

Because people would just make a ton of accounts to win the event items and transfer them into a main account

It will never happend. z8games will lose zp purchases and money by tradeing.
users and hackers will open more multyple accounts.

-and there is another problem also: if someone hack(very common) win a gun and transfer it to the main account,which account should be banned when he will be reported? -rookie?-main? or both? -and what action will be taken with the transferd item? It is tottaly wrong.

-Only if the IP bann system is put into practice will be fair for all. ban the IPs not the accounts ..and then do it!
if not, all the hackers will gain more guns in the main accounts they already have.meaning more cheating and more benefits for hackers.

-The only logical system i can think is a system for the temporary guns we have for 1000 days or more,in order to delete them.
