It is easy enough to block and individual IP or a malformed UA that you find doing things you don't want them to do but what do you do with IPs inside AT&T or Verizon that use a common vanilla agent? I am blocking individual IPs, I just don't think that is a very reliable defense when I see my own IP change daily and even in the same day. Do most Communications ISP clients have unique static IPs?
