Edit : The Digital Millennium Copyright Act (DMCA) prohibits circumventing an effective technological means of control that restricts access to a copyrighted work. I guess that would apply here.
I remember some guy that wrote a WoW bot and got sued using the DMCA, with the argument that his bot was circumventing the anti-cheat and the anti-cheat could be seen as a 'mechanism protecting copyrighted material', because it was safeguarding access to the game servers, the servers were generating parts of the game world (such as sounds) dynamically, and those were under copyright... Wild stuff.

Or, looking at it the other way, if you put a small sticker that says "do not do X" and even one person follows that, isn't that therefore an "effective" method?
It doesn't if you're not in the US.
