If someone threatens to kill me, should I just let it go?
If someone claims to have hacked my e-mail, and stolen my address along with other information (not mentioning posting some of it online to threaten me and my friends), should I not be serious about it?
If the same person also attempts to shut me out from PCDVD by manipulating my IP, should I not be angry about it?
If I don't have these problems, I wouldn't need to type this on a public computer without any Chinese input methods.
If my enemy takes it seriously, I think I should too.
