It may be a bit sloppy, but really, in this case, it's a bit silly. To get full information on the closure, you have to click "Read the rest of this entry", and there's a comment below the entry that says the ban has been lifted.

If you didn't click to read the rest of it, you wouldn't know the full extent of the closure, and you would probably hop in the forum and ask, or ask a ranger or even ask somewhere else. And yeah, we did post to other sites as soon as we'd heard to get the word out.

So in this case, what's the worst that could happen? You're on Hawk and some noob comes up and calls you an asshole because you're climbing in what he thinks is a restricted area?

Sloppy, yeah. Something to get your panties in a bunch over? Not really.
