WordPress Spam - No Solution :(

Further to my last post the spam continues. It seems to only come in once a day, at this point, but certainly a huge amount of links and writes to the blog itself. It starts with:

Anoyone know about this?

I certainly do get the benefit for them - does hurt us doesn't it.

I am running out of ideas - Comments are very welcomed.
