That's traffic I want to block, and that's behaviour that I want to punish / discourage. If a set of users get caught up in that, even when they've just been given recycled IP addresses, then there's more chance to bring the shitty 'scraping as a service' behaviour to light, thus to hopefully disinfect it.
