Today in Google SERPs I saw "Web definitions for" before main results go. for example: http://www.google.com/search?hl=en&newwindow=1&safe=off&q=what+is+google&btnG=%D0%9F%D0%BE%D0%B8%D1%81%D0%BA&lr=

Can you tell me is this new feature?

>Something you wrote is blocked; please remove "ru/" if possible.

Why??? To block spam from .ru domain? :(

Igor, "what is" is a soft trigger for the define: operator.

And yes, I once blacklisted ".ru" because of the high spam to normal posts ratio containing that string. Unfortunately, there are other country domains (like Tonga) I had to block as well. I've removed .ru from the blacklist for now and will see how it goes.
