IP resolves to China (which I've already got the Country banned ) - name is quite original ;)
I see it running from 202.96.51.150 repeatedly (lanshanbot uses .146, .147, etc.), but it's good you've got it blocked basically by default. Akin to lanshanbot, bot is sneaky -- it'll ask for robots.txt and then completely ignore it.
(Both lanshanbot and bot are also undaunted by 403s so the IP block is on my nuke-via-firewall to-do list.)
