Anyone who has written or who reads about China issues has encountered the ChiCom Troll. I didn't realize there was such a distinct term for these people, i always called them "brainwashed fanatic spittle round the mouth haters" -- anyway here is an introduction to trolls that made it into the NYT.
Basically, for web savvy cats, all this is old news: the troll that "trolls" the web looking for his issue of consequence, unloading his trollish essence all over the post/article/thread etc then moving on to troll another site.
There are "cracker white supremacist trolls, anti-liberal republicunt trolls, sappy-crispy hippy trolls, yamaka-sportin jewish trolls" and so on.
this link right here concerns itself with the ChiCom troll.
PS the rest of this dude's blog is ... trollish.
