As with anything you develop, you must take responsibility for your own actions. From a technology standpoint, there is little to distinguish a beneficial webbot from one that does destructive things. The main difference is the intent of the developer (and how well you debug your scripts). Therefore, it's up to you to do constructive things with the information in this book and not violate copyright law, disrupt networks, or do anything else that would be troublesome or illegal. And if you do, don't call me.

Please reference Chapter 28 for insight into how to write webbots ethically. Chapter 28 will help you do this, but it won't provide legal advice. If you have questions, talk to a lawyer before you experiment.
