When such a post is removed, it's typically referred to by netizens as being "harmonized", a play on Hu Jintao's "Harmonious Society" slogan [2].
You should check out the archives of a site like chinasmack or chinahush[3], who have translated summaries of popular chinese message board topics and gives a good feel of the day-to-day life of a chinese netizen.

On the other hand, our website is bilingual, and we don't really need to monitor the english part since the government doesn't care...
That level of censorship boggles the mind...

According to wikipedia, this is on the 12th most popular site in China.
I think the censors operate on very crude keyword filters. As long as you avoid the few obvious keywords, it's not that easy to get caught. The domestic web sites get around the censor by agreeing to open backdoors for the filters, yet at the same time turn a blind eye to the real disruptive stuffs that got around it.
But it's a pretty bad sign when, seeing someone use the word "freedom", your immediate reaction is suspicion, trying to decide whether or not it shows that the speaker is an enemy. And that's how it must be for the Chinese internet police who make decisions like this one.
First users were forced to use a relay, then relay IP's started getting banned, and now I think that the government has found some method to prevent connections to the Tor network completely (I'm not sure how).
Slowly but surely the screws are being tightened, more and more of the western net is becoming unavailable. I guess already 30-35% of all sites linked to on HN are blocked.
So if it does get blocked its not for long.
I wish I could help you with more specific information off the top of my head, but I fortunately don't have to use relays. I am willing to do some research and share the results here if you like.

A real hot bed.
One upside is that Chinese people seem to be a little more tech savvy. ie. many of them are forced to learn about proxy servers so they can go around the blocking.
Edit: By Chinese facebook, I meant the Chinese CLONE of facebook. Facebook itself is totally blocked in China.
