I did just that for a while with a spare server I had. I set it up to literally only respond to bad bots. I know the crawlers don't care but it amused me at least. I tried to also keep redirecting slowly before it could time out. There was one bot that seemed to create a new instance each redirect so I could keep it in a loop for essentially ever. Just about every other bot only followed a few redirects before giving up. Fun times.
