I wrote a plugin for node.js/express that performs basic bot detection and bans bots by IP address until they pay you some Bitcoin: project: https://github.com/timbowhite/botbouncer https://github.com/timbowhite/botbouncer simple demo: http://botbouncer.xyz/ http://botbouncer.xyz/ I ran it for awhile on some medium traffic websites that were being heavily scraped. It blocked thousands of IP addresses, but IIRC only received one Bitcoin payment.
