You don't get hacked. You get phished/keylogged. Both of which the victim has to be stupid to get.
That or if you're even stupider, you just give someone your password or leave yourself logged in somewhere where others can get your password/use your account.
Everyone in my class thinks hacking is using someone's account without their consent.
WHAY JOO RAGIN IN CAWPS?
I define hacking as the usage of an account you weren't meant to use.
