@Bamei
What you say is a fact. However, perceptions often outweigh facts. By casually saying that among a group of people are criminals, it paints the whole group.

@alien. I agree to a point, but Chinese people also visit this site. My wife has been pretty disgusted in the past and has stopped viewing. She also now has a much lower opinion of the expat community. People base their opinions/prejudices on what they see.
If you are a teacher, both employers and students read this stuff, and form opinions about you.

@ Gokunming.

My 2c.
Although your suggestion would work, it is also open to abuse by individuals who don't like a particular poster, or who wish to retaliate.

I think moderators should look at individual cases, and threads/posts/posters, on their merits/demerits.

If a post is an obvious troll or troll bait, then yes, shut it down. If a thread degenerates and there is thread s4itting by OPs, close it down. If a poster is a habitual troller, then perhaps it should be decided if that person is making any valuable contribution to the site, or whether they are doing potential harm to the reputation of the site or the expat community in Kunming.
I think the ultimate question is not about freedom of speech, it is about common decency. Does there are lots of places on the internet for such speech. Is Gokunming an appropriate platform for, lets face it, unpleasantness.

I guess you could say, 'It all blew over'.

There is a book club that posts on here and meets regularly. There is no reason why you should not try to start a creative writing group. You could follow the same course, but this is not important. You do not all need to be following the same course, as this will allow you to cross pollinate ideas. I think there will already be creative writers, or those who want to become one, in Kunming.

Publish a classified ad on here, and start a Wechat group.

I think @lemon lover was being satirical.
