How to tell who is spidering

How can I tell who is spidering?

The Safari Back Office application (where you go to get usage information) will provide a Warnings Report showing the time (GMT-1) the abuse occurred, as well as the IP address of the user.
Note: if you are using a proxy server, this report will provide the IP address of the proxy. Most network administrators will keep a log of which user was assigned a particular IP address for a given time period. You can then contact that person directly to resolve the problem.
