To give an idea of the scale of the problem right now, I'm getting thousands of requests per minute to a new IP vs. about two requests per minute on the equivalent old IP, with over 60% of the latter being Baidu, but also a bit of Googlebot and other random bot and non-bot UAs.
It's common for malware to spoof the Googlebot user-agent since they know most webmasters won't block it. You might want to check whether the IPs you're seeing it from are really allocated to us -- if so, I'd be interested in tracking down why we're crawling your old IP. Damian
