Don't forget that if you have garbage software like QQ and/or 360 Safety Software or any kind of Chinese Anti-Virus software you are susceptible to being hacked by Chinese hackers as there are holes in the software which can allow your computer to be hijacked. Your email or ebay account can be used to attack those servers as I learned from personal experience when I was in China. If some forum bans your IP or your google email account gets suspended for "security violations" and you don't even know basic computer programming then that is something to be worried about. All expats who live in china and run these types of chinese software need to be mindful of this.
