You agree that the information on this website is copyrighted, and you therefore agree not to distribute this information

It seems like that's not a logically valid statement. Linking to a page on their website isn't a copyright violation (unless I'm mistaken). And the statement seems to be saying "you agree it is copyrighted and, because you agree it is copyrighted, you must also therefore be agreeing that you aren't allowed to link to it. Which doesn't follow. It seems like saying "you agree this ball is red and, therefore, you agree it is rubber"; the two things are effectively orthogonal.
