Sometime it is not security , it could be just bandwidth or CPU.

I have website small enough not to attract too many bot, but sometime, something very innocent can bring my website down.

For example, I put a php ical viewer.. and some crawler start loading the calendar page, taking up all the cpu cycle.

Human make error too, but we held them liable for lots of the mistakes they make.

Can we make the agent liable? or the company behind the model liable?
