Dis-information?
So, if you're running a pro-Tibet website that's likely to be targetted by these attacks you've got two options: 1) try and tighten your security or 2) seed the 'private' parts of the site with interesting fake documents that suggest that certain random people are secretly backing the pro-Tibet campaigns. Nothing too obvious, perhaps some middle-ranking regional officials and military officers, relatives of more senior officials etc. Who will believe their denials?
I love black propaganda!
