On the one hand, the whole "there's a secret visitor" thing is lame. If the recruit and the university don't want the name out there, then everyone is better off just leaving it alone and saying nothing. Besides, the vast majority of the time it'll eventually come out anyway, so the "journalist" can provide whatever context/information he has at that time. Otherwise, this bit can come off as "look at me" behavior and/or click-bait.
On the other hand, going crazy bananas over it on a message board is equally lame. It's one thing to question the post or even ask "why post anything at all if you can't share any of the details?" But it is something very different to act like a spoiled brat on an internet message board crying because the name wasn't provided.
IMO, Blabby and Big ****** both come out looking bad here.
