This is what blogging has become. They're like ants at a picnic, or worse. They are some form of Chinese.
I have nothing against China. But they are one of the most populous nations on Earth. And every morning when I wake up, they have invaded my blog and left gibberish for comments and I fail to understand their point.
I am never actually going to allow one of their comments -- it's all in Mandarin or some other dialect -- so what's their point anyway? I think we have to assume that this is all mechanized.
And that some Chinese computer geek has come up with an automated program, like a germ, that automatically does this. And that Google's security system cannot stop it. Knock yourselves out.
