I don't understand. So if a "good" bot and a "bad" bot swop IP
addresses, you start blocking the (presumably ex-) "good" bot, and now
allow the (presumably ex-) "bad" bot?

Right, but my question is, "what makes a bot nasty?"

If you know that, why would you care what it's user-agent string, IP
address, or anything else is?
