I've had solid success detecting bots with a really easy pattern--usage frequency. Humans don't make request after request for long periods of times, but bots almost all do. The time between requests is usually pretty consistent too, not a lot of humans wait X seconds between doing things. Or not take breaks (what are the odds a human has made a request every hour for 48 hours straight?).

It's important to realize that there are many kinds of bots. So just because you found some doesn't mean you've discovered them all!

  Of course, I just wanted to suggest another technique that might be helpful to someone. Just going by IP address like the OP led to me to find a lot of VPNs and the like that I didn't want to detect.
