After i sign up premium account with MEGAUPLOAD.COM located in China, few hours later i received many junk emails, day after day, all emails contains with stupid language, all subject and body contains with small square boxs couldn't read it. They break their own policy, this is china ways! after i emailed to complained i received more junk emails. Finally, i unregister my email account :-(.
