163.com

[Joe Quinn]

We've been getting hammered by spam from 163.com for quite a while now, 
and I really /really/ want to blacklist it, but it's one of the largest 
websites in the world.

Everything I have found on Google points to them being blatant spammers, 
down to the Wikipedia talk page. Does anyone else have them blacklisted? 
What would the list recommend?
