Last 5 minutes i spend looking at log files of thumblogger. It seems that someone identified as 'ichiro/2.0' is doing some strange things, he onces visits a couple pages of the forum, he than visits random blogs. I grepped through the old logs and found a lot hits 'ichiro/2.0', he seems to like do random things.
Google didn't really know the answer, but i found a funny log entry about 'ichiro/2.0'
