Based on the example in the post, that thinking might need to be extended to "someone happening to be using a blocklisted IP." I don't serve up zip bombs, but I've blocklisted many abusive bots using VPN IPs over the years which have then impeded legitimate users of the same VPNs.

This is William Gibson's "black ICE" becoming real, and I love it.
