Wasn't half of weev's charge for unauthorized access related to him scripting up automated GET requests? It's not clear to me that it is definitely legal IANAL
I found the article overall useful. It seems to me that this issue is still not completely resolved, esp world-wide. The author gives disclaimer that they are not a lawyer, and then give what seems like their opinions. They give a scattering of references to court cases. But it seems they could have done a better job of giving proof for their claims. (UPDATE: The latter part of the article does better than the first.)
The author here. I actually am a lawyer. I just wanted to make it clear that I'm not "your" lawyer and therefore can't give advice on your specific use-case. Thanks for feedback. Might want to clarify that.
