The idea that they're allowed to restrict it at all is inherently silly, though. I mean, as written, it seems to imply that I may not link to anyone else's profile...

I consider that kind of restriction inherently unconsionable, regardless of the nature of the parties involved.

EDIT: I should also note that you appear to be violating them in your post, as I did not see an exception for such pages as that, though "deep linking" is one of those vague things that means whatever they want it to mean. Anything but the home page can be argued to be "deep" but different people have very different ideas on the subject and there's no inherent or technological meaning behind how deep a link must be before being considered a "deep link." So they don't even give you proper notice of which links they do and do not forbid.

So not only is it dumb in general, it's vague enough to make every link not pre-approved by Linked-In suspect, which is something I would object to for that very reason.
