I have explained the workings of some additional services and tools to the forum users before elsewhere on this forum (jsunpack, bad iFrame scanner, malzilla, de-obfuscation, online check of mainland China sites: http://www.knownsec.com/en/index.html
etc. specific users here know what these are all about and under what specific precautionairy circumstances they can use them) - but a nice additional listing is given here in the following forum thread by various posters: http://www.malwaredomainlist.com/forums/index.php?topic=1544.0
That is so and probably because the results are only for sites from mainland China exclusively.
There is also an english version of that page. And if the page results are in Chinese use Google Translate and load the page from Chinese to English for instance,
