There seems to be a small epidemic of blog spam coming in from apparently Polish sites. The comments take a variety of forms, but usually look something like this:
Thanks for very interesting article. btw. I really enjoyed reading all of your posts. It’s interesting to read ideas, and observations from someone else’s point of view… makes you think more. So please keep up the great work. Greetings
Sometimes they ask for permission to translate the article into Polish.
You may want to keep an eye out for these. Akismet seems to be missing a lot of them, and at first glance they seem like a real comment. However Googling some of the phrases makes it apparent that they’re spam. The exact wording varies.
