The only way to prove it would be to set up your logs to show the cookies contained in requests, and you will note that the spiders never send a request containing a cookie, which is the mechanism that maintains state. (The web is really stateless, the only way to simulate state other than AJAX is with cookies) In addition, if you use sessions, a session will typically expire before the next visit of a spider.
