My Mysterious Russian Readers

I have become puzzled of late by the large (relatively) number of readers that Blogger tells me I have in Russia. Russia has long been one of the top 5 countries in these statistics, but in the past few months it has surged far past other non-U.S. countries; above is the statistics for the past week.Yet when I look at referring sites I see numerous hits for the French and German versions of Google but none for the Russian. Is this all bots, doing insidious bot things?

If any actual Russian readers could enlighten me I would be grateful.
