In my de-spammer, I have a category of email I call "non-roman". This is all email in alphabets that I cannot read. Maybe it's spam, maybe it isn't, but if I can't read it, I'll never know.
In the last week or so, there has been a huge rise in spam in Chinese. This is only part of what arrived in the last several hours. Over the same time period, there were only 24 spams that weren't in Chinese.
