Why k2 can banned all 10 account

Today, i play warrock and use hack, i only use 1 hack and 1 acc. But i dont know why K2 can banned 10 acc other of me?

they banned your ISP (internet service provider) address probably.

they do that when repeat hackers are caught so many times....

sorry dude!

Maybe your acc has been used in many other IP's

all ISP addresses are unique for each computer/household.
(like a phone number for different houses)

so, considering that....

i'm pretty sure that nobody else can use your ISP address.

your ISP address registers inside your computer/modem and that is what allows you to go online....
(like a key to a lock)

i think he has just hacked too many times!
