This question already has an answer here:
We love our Stack Exchange and don't like to see it under attack like this.
Many of us are programmers and many of us know stuff about languages, including Chinese. There's probably a good few who are both programmers and know about Chinese and even a few with experience in Bayesian filtering, SPAM detecting, etc.
How can we help?
(I'm seeing the Spam attack on my main site, Travel.SE, which doesn't block Chinese characters like many sites can. I imagine the problem is also bad over at Chinese.SE)
