From BBC News:
China is using an increasing number of paid “internet commentators” in a sophisticated attempt to control public opinion.
These commentators are used by government departments to scour the internet for bad news – and then negate it.
They post comments on websites and forums that spin bad news into good in an attempt to shape public opinion.
Chinese leaders seem aware that the internet – the only public forum where views can be freely expressed – needs close attention.
